88-397: The damaru is typically made of wood, metal with leather damaru heads at both ends. The resonator is made of brass. The height of the damaru is 6 inches and weight varies from 250 to 330 gm. Its height ranges from a few inches to a little over one foot. It is played single-handedly. The strikers are typically beads fastened to the ends of leather cords around the waist of the damaru. Knots in

176-420: A drying and softening operation, and may include splitting, shaving, dyeing , whitening or other methods. For some leathers, tanners apply a surface coating, called "finishing". Finishing operations can include oiling, brushing, buffing, coating, polishing, embossing, glazing , or tumbling , among others. Leather can be oiled to improve its water resistance. This currying process after tanning supplements

264-432: A flexible form that does not become putrid when rewetted. Many tanning methods and materials exist. The typical process sees tanners load the hides into a drum and immerse them in a tank that contains the tanning "liquor". The hides soak while the drum slowly rotates about its axis, and the tanning liquor slowly penetrates through the full thickness of the hide. Once the process achieves even penetration, workers slowly raise

352-415: A liminal zone on the borders between fields and forests. Their rites involved the conjunction of sexual practices and Buddhist mandala visualization with ritual accoutrements made from parts of the human body, so that control may be exercised over the forces hindering the natural abilities of the siddha to manipulate the cosmos at will. At their most extreme, siddhas also represented a defensive position within

440-459: A long sash or tail called a chöpen. The chöpen is attached to the end of the drum's handle so that it waves about while the drum is being played. They are most commonly made of brocade or silk using the colors of the tantric elements. On smaller damaru, the chöpen is usually found without adornment, but on chöd damaru, the tail will often feature several items which have been sewn onto the fabric. These adornments commonly include but are not limited to:

528-532: A mantra. Vajrayāna Buddhists developed a large corpus of texts called the Buddhist Tantras , some of which can be traced to at least the 7th century CE but might be older. The dating of the tantras is "a difficult, indeed an impossible task" according to David Snellgrove . Some of the earliest of these texts, Kriya tantras such as the Mañjuśrī-mūla-kalpa ( c.  6th century ), teach

616-594: A movement called Sahaja -siddhi developed in the 8th century in Bengal . It was dominated by long-haired, wandering mahasiddhas who openly challenged and ridiculed the Buddhist establishment. The mahasiddhas pursued siddhis , magical powers such as flight and extrasensory perception as well as spiritual liberation. Ronald M. Davidson states that Buddhist siddhas demonstrated the appropriation of an older sociological form—the independent sage/magician, who lived in

704-497: A one-piece, double-sided (two-headed) bell shape, size varies from 8 inches to 12 inches in diameter. Usually featuring only a thin veneer of varnish, so that the grain of the wood shows, they come the common red (marpo), black (nakpo) or rare yellow (serpo) type of acacia, and are very occasionally painted with skulls, the eight charnel grounds, or other symbols. The waist or belt is traditionally made of leather, though often brocades are used. A set of mantras are traditionally painted on

792-540: A polished silver mirror or melong , a set of small bells, strips of tiger and/or leopard skin, one or more precious stones (i.e. dzi bead ), and any number of small brass trinkets. Leather Leather is a strong, flexible and durable material obtained from the tanning , or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle , sheep , goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators. Leather can be used to make

880-642: A properly managed facility. A review of the total pollution load decrease achievable according to the United Nations Industrial Development Organization posts precise data on the abatement achievable through industrially proven low-waste advanced methods, while noting, "even though the chrome pollution load can be decreased by 94% on introducing advanced technologies, the minimum residual load 0.15 kg/t raw hide can still cause difficulties when using landfills and composting sludge from wastewater treatment on account of

968-535: A standard right hand accompaniment to the bell, held in the left hand. Usually used to together as an accent or punctuation during various tantric practices, the drum can also keep time during entire passages. For the solo practitioner, it is an essential tool, while in larger assemblies, only the presiding Rinpoches and chant masters use them, in concert with the long horns ( radung ), short horns ( gyaling ), large cymbals ( silnyen and rolmo ) and large temple drums ( lag-na ). The Chöd damaru (or chöda )

1056-430: A variety of items, including clothing, footwear, handbags, furniture, tools and sports equipment, and lasts for decades. Leather making has been practiced for more than 7,000 years and the leading producers of leather today are China and India. Critics of tanneries claim that they engage in unsustainable practices that pose health hazards to the people and the environment near them. The leather manufacturing process

1144-628: A wet cloth or soaking the leather in water. Various treatments are available such as conditioners . Saddle soap is used for cleaning, conditioning, and softening leather. Leather shoes are widely conditioned with shoe polish . Due to its high resistance to abrasion and wind, leather found a use in rugged occupations. The enduring image of a cowboy in leather chaps gave way to the leather-jacketed and leather-helmeted aviator . When motorcycles were invented, some riders took to wearing heavy leather jackets to protect from road rash and wind blast; some also wear chaps or full leather pants to protect

1232-407: Is "obscured by discursive thought". This doctrine is often associated with the idea of the inherent or natural luminosity ( Skt: prakṛti-prabhāsvara-citta , T. ’od gsal gyi sems ) or purity of the mind ( prakrti-parisuddha ). Another fundamental theory of Tantric practice is that of transformation. In Vajrayāna, negative mental factors such as desire, hatred, greed, pride are used as part of

1320-677: Is a Buddhist tradition of tantric practice that developed in Medieval India . Tantrism, which originated within Hinduism during the first millennium CE, significantly influenced South Asian Mahāyāna Buddhism, giving rise to distinct Buddhist tantric traditions. Emerging in the 7th century CE, these traditions spread across Southeast, East, and Central Asia, leading to distinct East Asian and Tibetan practices. Vajrayāna practices are connected to specific lineages in Buddhism, through

1408-523: Is a method which works faster. Various classifications are possible when distinguishing Vajrayāna from the other Buddhist traditions. Vajrayāna can be seen as a third yana , next to Śrāvakayāna and Mahayana . Vajrayāna can be distinguished from the Sutrayana . The Sutrayana is the method of perfecting good qualities, where the Vajrayāna is the method of taking the intended outcome of Buddhahood as

1496-615: Is a mythical weapon associated with Indra which was said to be indestructible and unbreakable (like a diamond) and extremely powerful (like thunder). Thus, the term is variously translated as Diamond Vehicle, Thunderbolt Vehicle, Indestructible Vehicle and so on. Chinese Esoteric Buddhism it is generally known by various terms such as Zhēnyán ( Chinese : 真言, literally "true word", referring to mantra), Tángmì or Hanmì (唐密 - 漢密, " Tang Esotericism" or " Han Esotericism") , Mìzōng (密宗, "Esoteric Sect") or Mìjiao (Chinese: 密教; Esoteric Teaching). The Chinese term mì 密 ("secret, esoteric")

1584-416: Is a process that stabilizes the proteins , particularly collagen , of the raw hide to increase the thermal, chemical and microbiological stability of the hides and skins, making it suitable for a wide variety of end applications. The principal difference between raw and tanned hides is that raw hides dry out to form a hard, inflexible material that, when rewetted, will putrefy , while tanned material dries to

1672-420: Is a specialized form of damaru. It is generally larger in circumference and has a more round shape than its smaller counterpart. The Chöd damaru is used in the tantric practice of Chod . With no known antecedent, the chod is traditionally made of acacia wood (seng deng), though a variety of woods are acceptable, as long as the tree is not toxic and does not possess thorns or other negative attributes. Made as

1760-609: Is a translation of the Sanskrit term Guhya ("secret, hidden, profound, abstruse"). In Japan , Buddhist esotericism is known as Mikkyō ( 密教 , secret teachings) or by the term Shingon (a Japanese rendering of Zhēnyán ), which also refers to a specific school of Shingon-shū ( 真言宗 ) . The term "Esoteric Buddhism" is first used by Western occultist writers, such as Helena Blavatsky and Alfred Percy Sinnett , to describe theosophical doctrines passed down from "supposedly initiated Buddhist masters." Tantric Buddhism

1848-534: Is also used for falconry jesses, soccer footwear, (e.g. Adidas Copa Mundial ) and boxing speed bags. Although originally raised for their feathers in the 19th century, ostriches are now more popular for both meat and leather. Ostrich leather has a characteristic "goose bump" look because of the large follicles where the feathers grew. Different processes produce different finishes for many applications, including upholstery, footwear, automotive products, accessories, and clothing. In Thailand , stingray leather

1936-553: Is associated with groups of wandering yogis called mahasiddhas in medieval India . According to Robert Thurman , these tantric figures thrived during the latter half of the first millennium CE. According to John Myrdhin Reynolds, the mahasiddhas date to the medieval period in North India and used methods that were radically different from those used in Buddhist monasteries, including practicing on charnel grounds . Since

2024-438: Is believed that Sanskrit language was recognized by the drumbeats of the damaru (see Shiva Sutra for the sounds), and his performance of the cosmic dance of tandava . The damaru is used by itinerant musicians of all stripes, due to its small portable size. In the shield shape of some damaru s, the triangular upward representation also symbolizes male procreativity (the lingam ), and the downward round representation symbolizes

2112-494: Is bound, by passion too it is released, but by heretical Buddhists this practice of reversals is not known. The Hevajra further states that "one knowing the nature of poison may dispel poison with poison." As Snellgrove notes, this idea is already present in Asanga 's Mahayana-sutra-alamkara-karika and therefore it is possible that he was aware of Tantric techniques, including sexual yoga. According to Buddhist Tantra, there

2200-411: Is called bating. Lipases are used in the degreasing operation to hydrolyze fat particles embedded in the skin. Amylases are used to soften skin, to bring out the grain, and to impart strength and flexibility to the skin. These enzymes are rarely used. The natural fibers of leather break down with the passage of time. Acidic leathers are particularly vulnerable to red rot , which causes powdering of

2288-530: Is developed. Other early tantras include the Mahāvairocana Abhisaṃbodhi and the Guhyasamāja (Gathering of Secrets). The Guhyasamāja is a Mahayoga class of Tantra, which features forms of ritual practice considered "left-hand" ( vamachara ) such as the use of taboo substances like alcohol, consort practices, and charnel ground practices which evoke wrathful deities . Ryujun Tajima divides

2376-405: Is divided into three fundamental subprocesses: preparatory stages, tanning, and crusting. A further subprocess, finishing, can be added into the leather process sequence, but not all leathers receive finishing. The preparatory stages are when the hide is prepared for tanning. Preparatory stages may include soaking, hair removal, liming , deliming , bating , bleaching , and pickling . Tanning

2464-534: Is more common for a yogi or yogini to use an imagined consort (a buddhist tantric deity, i.e. a yidam). These later tantras such as the Hevajra Tantra and the Chakrasamvara are classed as " Yogini tantras" and represent the final form of development of Indian Buddhist tantras in the ninth and tenth centuries. The Kalachakra tantra developed in the 10th century. It is farthest removed from

2552-444: Is more complex than a simple process of religious imitation and textual appropriation. There can be no question that the Buddhist tantras were heavily influenced by Kapalika and other Saiva movements, but the influence was apparently mutual. Perhaps a more nuanced model would be that the various lines of transmission were locally flourishing and that in some areas they interacted, while in others they maintained concerted hostility. Thus

2640-414: Is no longer a source, and their creation and export from Nepal are banned, because of the acquiring of human bone through illegal practices. One still does find occasionally those with painted skins and without the proper mantras or other characteristics. The symbolism and energetic properties of the drums is extensive. These human skull damaru or chang te'u are used in a wide range of Vajrayana ritual, as

2728-496: Is no strict separation of the profane or samsara and the sacred or nirvana , rather they exist in a continuum. All individuals are seen as containing the seed of enlightenment within, which is covered over by defilements . Douglas Duckworth notes that Vajrayana sees Buddhahood not as something outside or an event in the future, but as immanently present. Indian Tantric Buddhist philosophers such as Buddhaguhya , Vimalamitra , Ratnākaraśānti and Abhayakaragupta continued

2816-672: Is not specifically Buddhist, Shaiva or Vaishnava . According to Alexis Sanderson , various classes of Vajrayāna literature developed as a result of royal courts sponsoring both Buddhism and Shaivism. The relationship between the two systems can be seen in texts like the Mañjusrimulakalpa , which later came to be classified under Kriya tantra , and states that mantras taught in the Shaiva, Garuda and Vaishnava tantras will be effective if applied by Buddhists since they were all taught originally by Manjushri . Sanderson notes that

2904-452: Is one of the most exploited reptile species in the world in the leather trade. However, it is not endangered and while monitored, trade is legal in most South American countries. Kangaroo leather is used to make items that must be strong and flexible. It is the material most commonly used in bullwhips . Some motorcyclists favor kangaroo leather for motorcycle leathers because of its light weight and abrasion resistance. Kangaroo leather

2992-522: Is the superiority of Tantric methods, which provide a faster vehicle to liberation and contain many more skillful means ( upaya ). The importance of the theory of emptiness is central to the Tantric Buddhist view and practice. The Buddhist emptiness view sees the world as being fluid, without an ontological foundation or inherent existence, but ultimately a fabric of constructions. Because of this, tantric practice such as self-visualization as

3080-522: Is to become a Sammāsambuddha (fully awakened Buddha ); those on this path are termed Bodhisattvas . As with the Mahayana, motivation is a vital component of Vajrayāna practice. The Bodhisattva-path is an integral part of the Vajrayāna, which teaches that all practices are to be undertaken with the motivation to achieve Buddhahood for the benefit of all sentient beings. In the vehicle of Sutra Mahayana,

3168-545: Is used in wallets and belts. Stingray leather is tough and durable. The leather is often dyed black and covered with tiny round bumps in the natural pattern of the back ridge of an animal. These bumps are then usually dyed white to highlight the decoration. Stingray rawhide is also used as grips on Chinese swords, Scottish basket hilted swords, and Japanese katanas . Stingray leather is also used for high abrasion areas in motorcycle racing leathers (especially in gloves, where its high abrasion resistance helps prevent wear through in

3256-463: The Hīnayāna ) and Mahāyāna (a.k.a. Pāramitāyāna ). There are several Buddhist tantric traditions that are currently practiced, including Tibetan Buddhism , Chinese Esoteric Buddhism , Shingon Buddhism and Newar Buddhism . Historically, there were also other esoteric Buddhist traditions, such as that of maritime Southeast Asia , which are no longer practiced today. In India, the initial term

3344-712: The Guhyasiddhi of Padmavajra, a work associated with the Guhyasamaja tradition , which prescribes acting as a Shaiva guru and initiating members into Saiva Siddhanta scriptures and mandalas. Sanderson says that the Samvara tantra texts adopted the pitha list from the Shaiva text Tantrasadbhāva , introducing a copying error where a deity was mistaken for a place. Ronald M. Davidson meanwhile, argues that Sanderson's arguments for direct influence from Shaiva Vidyapitha texts are problematic because "the chronology of

3432-606: The Mantrayana leads one to Buddhahood in a single lifetime. According to the literature, the mantra is an easy path without the difficulties innate to the Paramitayana . Mantrayana is sometimes portrayed as a method for those of inferior abilities. However the practitioner of the mantra still has to adhere to the vows of the Bodhisattva . The goal of spiritual practice within the Mahayana and Vajrayāna traditions

3520-561: The Vidyapitha tantras is by no means so well established" and that "the available evidence suggests that received Saiva tantras come into evidence sometime in the ninth to tenth centuries with their affirmation by scholars like Abhinavagupta (c. 1000 c.e.)" Davidson also notes that the list of pithas or sacred places "are certainly not particularly Buddhist, nor are they uniquely Kapalika venues, despite their presence in lists employed by both traditions." Davidson further adds that like

3608-488: The "path of the cause" is taken whereby a practitioner starts with his or her potential Buddha-nature and nurtures it to produce the fruit of Buddhahood. In the Vajrayāna, the "path of the fruit" is taken whereby the practitioner takes his or her innate Buddha-nature as the means of practice. The premise is that since we innately have an enlightened mind, practicing seeing the world in terms of ultimate truth can help us to attain our full Buddha-nature. Experiencing ultimate truth

3696-589: The 1970s and 80s) are well known for wearing leather clothing. Extreme metal bands (especially black metal bands) and Goth rock groups have extensive black leather clothing. Leather has become less common in the punk community over the last three decades, as there is opposition to the use of leather from punks who support animal rights . Many cars and trucks come with optional or standard leather or "leather faced" seating. In countries with significant populations of individuals observing religions which place restrictions on material choices, vendors typically clarify

Operating on the margins of both monasteries and polite society, some adopted

3872-521: The Buddhists, the Shaiva tradition was also involved in the appropriation of Hindu and non-Hindu deities, texts and traditions, an example being "village or tribal divinities like Tumburu". Davidson adds that Buddhists and Kapalikas as well as other ascetics (possibly Pasupatas ) mingled and discussed their paths at various pilgrimage places and that there were conversions between the different groups. Thus he concludes: The Buddhist-Kapalika connection

The skull (thöpa) damaru is made from a male and female skull bone or calvarium , cut well above the area of the ear, and joined at their apex. Inside, male and female mantras are appropriately inscribed in gold. The skins are traditionally cured by burying them with copper and other mineral salts, and special herbal formulas for about two weeks. These are then stretched and applied to

These reached

4136-600: The Vajrayāna Yogini tantras draw extensively from the material also present in Shaiva Bhairava tantras classified as Vidyapitha . Sanderson's comparison of them shows similarity in "ritual procedures, style of observance, deities, mantras, mandalas, ritual dress, Kapalika accouterments like skull bowls, specialized terminology, secret gestures, and secret jargons. There is even direct borrowing of passages from Shaiva texts." Sanderson gives numerous examples such as

4224-435: The adherents and texts of Vajrayāna claim these teachings have been passed down by an unbroken lineage going back to the historical Buddha ( c.  the 5th century BCE ) or to other mythical Buddhas and bodhisattvas (e.g. Vajrapani ). According to Vajrayāna scriptures, the term Vajrayāna refers to one of three vehicles or routes to enlightenment , the other two being the Śrāvakayāna (also known pejoratively as

Tantrism originated within Hinduism and significantly influenced early South Asian Mahāyāna Buddhist practices, contributing to the emergence of unique Buddhist tantric traditions. These Buddhist tantric traditions, which developed in the 7th century CE, spread quickly across Southeast, East, and Central Asia, resulting in

4400-490: The deity is seen as being no less real than everyday reality, but a process of transforming reality itself, including the practitioner's identity as the deity. As Stephan Beyer notes, "In a universe where all events dissolve ontologically into Emptiness, the touching of Emptiness in the ritual is the re-creation of the world in actuality". The doctrine of Buddha-nature , as outlined in the Ratnagotravibhāga of Asanga ,

4488-424: The earlier Buddhist traditions, and incorporates concepts of messianism and astrology not present elsewhere in Buddhist literature. According to Ronald M. Davidson, the rise of Tantric Buddhism was a response to the feudal structure of Indian society in the early medieval period (ca. 500–1200 CE) which saw kings being divinized as manifestations of gods. Likewise, tantric yogis reconfigured their practice through

4576-679: The event of an accident). For a given thickness, fish leather is typically much stronger due to its criss-crossed fibers. Leather produces some environmental impact, most notably due to: Estimates of the carbon footprint of bovine leather range from 65 to 150 kg of CO 2 equivalent per square meter of production. One ton of hide or skin generally produces 20 to 80 m of waste water, including chromium levels of 100–400 mg/L, sulfide levels of 200–800 mg/L, high levels of fat and other solid wastes, and notable pathogen contamination. Producers often add pesticides to protect hides during transport. With solid wastes representing up to 70% of

4664-439: The female procreativity (the yoni ). Symbolically, the creation of the world begins when the lingam and yoni meet at the midpoint of the damaru , and the destruction takes place when they separate from each other. In the post-Mauryan period a tribal society at Kosambi (modern Allahabad district ) made cast copper coinage with and without punchmarks. Their coinage resemble the damaru-drum. All such coinage has been attributed to

4752-452: The following grades: The term "genuine leather" does not describe a specific grade. The term often indicates split leather that has been extensively processed, and some sources describe it as synonymous with bicast leather, or made from multiple splits glued together and coated. In some countries, when it is the description on a product label the term means nothing more than "contains leather"; depending on jurisdiction, regulations limit

4840-756: The formation of various distinct traditions in East Asia and Tibet. There are other Mahāyāna sutras which contain "proto-tantric" material such as the Gandavyuha and the Dasabhumika which might have served as a central source of visual imagery for Tantric texts. Later Mahāyāna texts like the Kāraṇḍavyūha Sūtra ( c.  4th –5th century CE) expound the use of mantras such as Om mani padme hum , associated with vastly powerful beings like Avalokiteshvara . The popular Heart Sutra also includes

4928-657: The ideal manufacture of the damaru, and as still described in the definitive modern work, the "Mindroling Handbook of Vajrayana Implements". Those manufactured in India and Nepal are made of indeterminate and cheap woods, with painted skins, often no interior mantras, and altogether deviating from the many other essentials, as prescribed in technical literature such as the Mindroling Handbook. Such copies are now widespread and in use by Eastern monastics and Western students. Damaru of all kinds are traditionally paired with

5016-466: The influence was both sustained and reciprocal, even in those places where Buddhist and Kapalika siddhas were in extreme antagonism. Davidson also argues for the influence of non-Brahmanical and outcaste tribal religions and their feminine deities (such as Parnasabari and Janguli). According to several Buddhist tantras as well as traditional Tibetan Buddhist sources, the tantras and the Vajrayana

Chemical damage can also occur from exposure to environmental factors, including ultraviolet light, ozone, acid from sulfurous and nitrous pollutants in the air, or through a chemical action following any treatment with tallow or oil compounds. Both oxidation and chemical damage occur faster at higher temperatures. There are few methods to maintain and clean leather goods properly such as using damp cloth and avoid using

The question of the origins of early Vajrayāna has been taken up by various scholars. David Seyfort Ruegg has suggested that Buddhist tantra employed various elements of a “pan-Indian religious substrate” which

Frequent oiling of leather, with mink oil , neatsfoot oil , or a similar material keeps it supple and improves its lifespan dramatically. Tanning processes largely differ in which chemicals are used in the tanning liquor. Some common types include: In general, leather is produced in

5720-453: The path. As noted by French Indologist Madeleine Biardeau, the tantric doctrine is "an attempt to place kama , desire, in every meaning of the word, in the service of liberation." This view is outlined in the following quote from the Hevajra tantra : Those things by which evil men are bound, others turn into means and gain thereby release from the bonds of existence. By passion the world

5808-471: The path. Vajrayāna can also be distinguished from the paramitayana. According to this schema, Indian Mahayana revealed two vehicles ( yana ) or methods for attaining enlightenment: the method of the perfections ( Paramitayana ) and the method of mantra ( Mantrayana ). The Paramitayana consists of the six or ten paramitas , of which the scriptures say that it takes three incalculable aeons to lead one to Buddhahood. The tantra literature, however, says that

5896-569: The practice of Tantra focuses on the transformation of poisons into wisdom, the yogic circles came together in tantric feasts , often in sacred sites ( pitha ) and places ( ksetra ) which included dancing, singing, consort practices and the ingestion of taboo substances like alcohol, urine, and meat. At least two of the mahasiddhas cited in the Buddhist literature are comparable with the Shaiva Nath saints ( Gorakshanath and Matsyendranath ) who practiced Hatha Yoga . According to Schumann,

Some accounts also maintain Padmasambhava is a direct reincarnation of Buddha Shakyamuni. According to Alex Wayman , the philosophical view of the Vajrayana is based on Mahayana Buddhist philosophy , mainly the Madhyamaka and Yogacara schools. The major difference seen by Vajrayana thinkers

Deerskin is widely used in work gloves and indoor shoes. Reptilian skins, such as alligator , crocodile, and snake , are noted for their distinct patterns that reflect the scales of their species. This has led to hunting and farming of these species in part for their skins. The Argentine black and white tegu

6248-542: The source of leather in their products. Such labeling helps facilitate religious observance, so, for example, a Muslim will not accidentally purchase pigskin or a Hindu can avoid cattleskin. Such taboos increase the demand for religiously neutral leathers such as ostrich and deer . Judaism forbids the comfort of wearing leather shoes on Yom Kippur , Tisha B'Av , and during mourning. Also, see Leather in Judaism , Teffilin and Torah Scroll . Jainism prohibits

6336-400: The surface and a change in consistency. Damage from red rot is aggravated by high temperatures and relative humidities. Although it is chemically irreversible, treatments can add handling strength and prevent disintegration of red rotted leather. Exposure to long periods of low relative humidities (below 40%) can cause leather to become desiccated, irreversibly changing the fibrous structure of

6424-532: The tantras into those which were "a development of Mahāyānist thought" and those "formed in a rather popular mould toward the end of the eighth century and declining into the esoterism of the left", this "left esoterism" mainly refers to the Yogini tantras and later works associated with wandering yogis. This practice survives in Tibetan Buddhism, but it is rare for this to be done with an actual person. It

6512-455: The tantric view continued to be debated in medieval Tibet. Tibetan Buddhist Rongzom Chokyi Zangpo (1012–1088) held that the views of sutra such as Madhyamaka were inferior to that of tantra, which was based on basic purity of ultimate reality. Tsongkhapa (1357–1419) on the other hand, held that there is no difference between Vajrayāna and other forms of Mahayana in terms of prajnaparamita (perfection of insight) itself, only that Vajrayāna

According to contemporary historical scholarship, Vajrayāna practice originated in the tantric era of medieval India ( c.  the 5th century CE onwards ). However, traditionally,

6688-440: The term's use in product labelling. Today, most leather is made of cattle (cow) hides, which constitute about 65% of all leather produced. Other animals that are used include sheep (about 13%), goats (about 11%), and pigs (about 10%). Obtaining accurate figures from around the world is difficult, especially for areas where the skin may be eaten. There are significant regional differences in leather production: i.e. goat leather

6776-706: The tradition of Buddhist philosophy and adapted it to their commentaries on the major Tantras. Abhayakaragupta's Vajravali is a key source in the theory and practice of tantric rituals. After monks such as Vajrabodhi and Śubhakarasiṃha brought Tantra to Tang China (716 to 720), tantric philosophy continued to be developed in Chinese and Japanese by thinkers such as Yi Xing and Kūkai . Likewise in Tibet , Sakya Pandita (1182–28 – 1251), as well as later thinkers like Longchenpa (1308–1364) expanded on these philosophies in their tantric commentaries and treatises. The status of

6864-499: The two sides, giving the skins their familiar blue or green mottled appearance. A collar of simple brocade, or copper or silver, has a hand-hold, and is the site of attachment of the beaters, whose knit cover represents two eyeballs. The skulls are also carefully chosen for their attributes and source. After the Tibetan diaspora in 1960, they began to be manufactured in India and Nepal, with a continued degradation of quality. Today, India

6952-1078: The use of leather, since it is obtained by killing animals. Many forms of artificial leather have been developed, usually involving polyurethane or vinyl coatings applied to a cloth backing. Many names and brands for such artificial leathers exist, including "pleather", a portmanteau of "plastic leather", and the brand name Naugahyde . Another alternative is cultured leather which is lab-grown using cell-culture methods, mushroom-based materials and gelatin-based textile made by upcycling meat industry waste. Leather made of fungi or mushroom-based materials are completely biodegradable. Tantra techniques (Vajrayana) New branches: Tantric techniques : Fourfold division: Twofold division: Thought forms and visualisation: Yoga : Vajrayāna ( Sanskrit : वज्रयान ; lit.

7040-482: The use of mantras and dharanis for mostly worldly ends including curing illness, controlling the weather and generating wealth. The Tattvasaṃgraha Tantra ( Compendium of Principles ), classed as a "Yoga tantra", is one of the first Buddhist tantras which focuses on liberation as opposed to worldly goals. In another early tantra, the Vajrasekhara (Vajra Peak), the influential schema of the five Buddha families

7128-462: The weekend of 8 April 2017 in the neighborhood. The higher cost associated with the treatment of effluents than to untreated effluent discharging leads to illegal dumping to save on costs. For instance, in Croatia in 2001, proper pollution abatement cost US$ 70–100 per ton of raw hides processed against $ 43/t for irresponsible behavior. In November 2009, one of Uganda's main leather making companies

7216-676: The wet weight of the original hides, the tanning process represents a considerable strain on water treatment installations. Leather biodegrades slowly—taking 25 to 40 years to decompose . However, vinyl and petrochemical-derived materials take 500 or more years to decompose. Tanning is especially polluting in countries where environmental regulations are lax, such as in India, the world's third-largest producer and exporter of leather. To give an example of an efficient pollution prevention system, chromium loads per produced tonne are generally abated from 8 kg to 1.5 kg. VOC emissions are typically reduced from 30 kg/t to 2 kg/t in

7304-480: Was Mantranāya (Path of Mantras), and Mantrayāna (Mantra Vehicle). Later, other terms were adopted, like Vajrayāna. In Tibetan Buddhism practiced in the Himalayan regions of India , Nepal , and Bhutan , Buddhist Tantra is most often termed Vajrayāna (Tib. རྡོ་རྗེ་ཐེག་པ་, dorje tekpa , Wyl. rdo rje theg pa ) and Secret mantra (Skt. Guhyamantra , Tib. གསང་སྔགས་, sang ngak , Wyl. gsang sngags ). The vajra

7392-457: Was also an important theory which became the basis for Tantric views. As explained by the Tantric commentator Lilavajra, this "intrinsic secret (behind) diverse manifestation" is the utmost secret and aim of Tantra. According to Wayman this "Buddha embryo" ( tathāgatagarbha ) is a "non-dual, self-originated Wisdom ( jnana ), an effortless fount of good qualities" that resides in the mindstream but

7480-544: Was caught directly dumping waste water into a wetland adjacent to Lake Victoria . Enzymes like proteases , lipases , and amylases have an important role in the soaking, dehairing, degreasing, and bating operations of leather manufacturing. Proteases are the most commonly used enzymes in leather production. The enzyme must not damage or dissolve collagen or keratin , but should hydrolyze casein , elastin , albumin , globulin -like proteins, and nonstructural proteins that are not essential for leather making. This process

7568-592: Was dumping 22 tonnes of chromium-laden solid waste per day in the open. In the Hazaribagh neighborhood of Dhaka in Bangladesh , chemicals from tanneries end up in Dhaka's main river. Besides the environmental damage, the health of both local factory workers and the end consumer is also negatively affected. After approximately 15 years of ignoring high court rulings, the government shut down more than 100 tanneries

7656-557: Was historically called "Turkey" or "Morocco" due to its association with the Middle East, while pig skin had historically been used the most in Germany. Other animals mentioned below only constitute a fraction of a percent of total leather production. Horse hides are used to make particularly durable leathers. Shell cordovan is a horse leather made not from the outer skin but from an under layer, found only in equine species, called

7744-545: Was taught by the Buddha Shakyamuni , but only to some individuals. There are several stories and versions of how the tantras were disseminated. The Jñana Tilaka Tantra , for example, has the Buddha state that the tantras will be explained by the bodhisattva Vajrapani . One of the most famous legends is that of king Indrabhuti (also known as King Ja) of Oddiyana (a figure related to Vajrapani, in some cases said to be an emanation of him). Other accounts attribute
