A laboratory ( UK : / l ə ˈ b ɒr ə t ər i / ; US : / ˈ l æ b r ə t ɔːr i / ; colloquially lab ) is a facility that provides controlled conditions in which scientific or technological research, experiments , and measurement may be performed. Laboratories are found in a variety of settings such as schools, universities, privately owned research institutions, corporate research and testing facilities, government regulatory and forensic investigation centers, physicians' offices, clinics, hospitals, regional and national referral centers, and even occasionally personal residences.
101-498: The Federal Laboratory Consortium for Technology Transfer (FLC) is a U.S.-based nationwide network of federal laboratories that provides a forum to develop strategies and opportunities to help transfer laboratory mission technologies into commercial products for the global marketplace. The FLC was organized in 1974 and formally chartered by the Federal Technology Transfer Act of 1986 . Its host agency

They did not abandon the Ancient Greek philosophical idea that everything is composed of four elements , and they tended to guard their work in secrecy, often making use of cyphers and cryptic symbolism. In Europe, the 12th-century translations of medieval Islamic works on science and the rediscovery of Aristotelian philosophy gave birth to
303-408: A collection of deities that are each said to represent and protect a specific body part or region. Although those who practised Neidan prioritized meditation over external alchemical strategies, many of the same elixirs and constituents from previous Daoist alchemical schools of thought continued to be utilized in tandem with meditation. Eternal life remained a consideration for Neidan alchemists, as it
404-510: A flourishing tradition of Latin alchemy. This late medieval tradition of alchemy would go on to play a significant role in the development of early modern science (particularly chemistry and medicine ). Modern discussions of alchemy are generally split into an examination of its exoteric practical applications and its esoteric spiritual aspects, despite criticisms by scholars such as Eric J. Holmyard and Marie-Louise von Franz that they should be understood as complementary. The former

Scholarship on Indian alchemy is in the publication of The Alchemical Body by David Gordon White. A modern bibliography on Indian alchemical studies has been written by White. The contents of 39 Sanskrit alchemical treatises have been analysed in detail in G. Jan Meulenbeld 's History of Indian Medical Literature . The discussion of these works in HIML gives
606-424: A lab is contaminated, but often ends up in the contaminated waste, driving up energy costs for waste disposal. A good sorting and recycling system for non contaminated lab waste will allow lab users to act sustainably and correctly dispose of waste. As of 2021, there are numerous laboratories currently dedicating time and resources to move towards more sustainable lab practices at their facilities, e.g. MIT and
707-490: A more obvious connection to medicine. The philosopher's stone of European alchemists can be compared to the Grand Elixir of Immortality sought by Chinese alchemists. In the hermetic view, these two goals were not unconnected, and the philosopher's stone was often equated with the universal panacea ; therefore, the two traditions may have had more in common than initially appears. As early as 317 AD, Ge Hong documented
808-465: A new form of alchemy. Neidan emphasized appeasing the inner gods that inhabit the human body by practising alchemy with compounds found in the body, rather than the mixing of natural resources that was emphasized in early Dao alchemy. For example, saliva was often considered nourishment for the inner gods and did not require any conscious alchemical reaction to produce. The inner gods were not thought of as physical presences occupying each person, but rather
909-554: A receptionist would view the badge as useful, as it would help them locate members of staff during the day. Illustrating relations, researchers would also wear their badge due to informal pressures, such as not wanting to look like a spoil-sport, or not wanting to draw attention to themselves. Another finding is the resistance to change in a social organization. Staff members feel ill at ease when changing patterns of entitlement, obligation, respect, informal and formal hierarchy, and more. In summary, differences in attitude among members of

Chapter 13 of HIML, Various works on rasaśāstra and ratnaśāstra (or Various works on alchemy and gems ) gives brief details of a further 655 (six hundred and fifty-five) treatises. In some cases Meulenbeld gives notes on the contents and authorship of these works; in other cases references are made only to

While alchemy was not more important to him than other sciences and he did not produce allegorical works on the topic, he did consider it and astrology to be important parts of both natural philosophy and theology and his contributions advanced alchemy's connections to soteriology and Christian theology. Bacon's writings integrated morality, salvation, alchemy, and

While Hongjing did not deny the power of alchemical elixirs to grant immortality or provide divine protection, he ultimately found the Scripture of the Nine Elixirs to be ambiguous and spiritually unfulfilling, aiming to implement more accessible practising techniques. In the early 700s, Neidan (also known as internal alchemy) was adopted by Daoists as

The classical equipment includes tools such as Bunsen burners and microscopes as well as specialty equipment such as operant conditioning chambers , spectrophotometers and calorimeters . The title of laboratory is also used for certain other facilities where the processes or equipment used are similar to those in scientific laboratories. These notably include: In many laboratories, hazards are present. Laboratory hazards might include poisons ; infectious agents ; flammable , explosive , or radioactive materials; moving machinery ; extreme temperatures ; lasers , strong magnetic fields or high voltage . Therefore, safety precautions are vitally important. Rules exist to minimize

These writings were collected in the first centuries of the common era. The dawn of Western alchemy is sometimes associated with that of metallurgy , extending back to 3500 BC. Many writings were lost when the Roman emperor Diocletian ordered

By looking at the various interactions among staff members, we can determine their social position in the organization. As an example, administrators, in one lab of the study, do not have the right to ask the Locator where

One such device can consume up to the same amount of energy as a single-family household (25 kWh/day). Increasing the temperature to −70 °C makes it possible to use 40% less energy and still keep most samples safely stored. Minimizing the consumption of water can be achieved by changing from water-cooled condensers ( Dimroth condenser ) to air-cooled condensers ( Vigreux column ), which take advantage of

The latter interests historians of esotericism , psychologists , and some philosophers and spiritualists . The subject has also made an ongoing impact on literature and the arts. The word alchemy comes from old French alquemie , alkimie , used in Medieval Latin as alchymia . This name

Its principles restored the health of those who were ill beyond hope and gave back youth to fading old age. The goals of alchemy in India included
2121-498: Is still an open question whether these three strands share a common origin, or to what extent they influenced each other. The start of Western alchemy may generally be traced to ancient and Hellenistic Egypt , where the city of Alexandria was a center of alchemical knowledge, and retained its pre-eminence through most of the Greek and Roman periods. Following the work of André-Jean Festugière, modern scholars see alchemical practice in

Under this standard, a laboratory is required to produce a Chemical Hygiene Plan (CHP) which addresses the specific hazards found in its location, and its approach to them. In determining the proper Chemical Hygiene Plan for a particular business or laboratory, it is necessary to understand the requirements of the standard, evaluation of the current safety, health and environmental practices and assessment of

Albertus Magnus, a Dominican friar , is known to have written works such as the Book of Minerals where he observed and commented on the operations and theories of alchemical authorities like Hermes Trismegistus , pseudo-Democritus and unnamed alchemists of his time. Albertus critically compared these to

The most influential author in this regard was arguably Jabir. Jabir's ultimate goal was Takwin , the artificial creation of life in the alchemical laboratory, up to, and including, human life. He analysed each Aristotelian element in terms of four basic qualities of hotness , coldness , dryness , and moistness . According to Jabir, in each metal two of these qualities were interior and two were exterior. For example, lead

The four elements are simply the primary, and most general, qualities by means of which the amorphous and purely quantitative substance of all bodies first reveals itself in differentiated form." Later alchemists extensively developed

The most complete of their works, The Four Books of Pseudo-Democritus , were probably written in the first century AD.

According to the Egyptologist Wallis Budge , the Arabic word al-kīmiya ʾ actually means "the Egyptian [science]", borrowing from the Coptic word for "Egypt", kēme (or its equivalent in the Mediaeval Bohairic dialect of Coptic, khēme ). This Coptic word derives from Demotic kmỉ , itself from ancient Egyptian kmt . The ancient Egyptian word referred to both

Other commonalities shared between

Tracing the origins of the alchemical art in Egypt is complicated by the pseudepigraphic nature of texts from the Greek alchemical corpus. The treatises of Zosimos of Panopolis , the earliest historically attested author ( fl. c. 300 AD), can help in situating the other authors. Zosimus based his work on that of older alchemical authors, such as Mary

4747-502: The concept of social organization in laboratories. The main subject of the study revolved around the relationship between the staff of a laboratory (researchers, administrators, receptionists, technicians, etc.) and their Locator. A Locator is an employee of a Laboratory who is in charge of knowing where each member of the laboratory currently is, based on a unique signal emitted from the badge of each staff member. The study describes social relationships among different classes of jobs, such as
4848-613: The country and the colour "black" (Egypt was the "black Land", by contrast with the "red Land", the surrounding desert). Alchemy encompasses several philosophical traditions spanning some four millennia and three continents. These traditions' general penchant for cryptic and symbolic language makes it hard to trace their mutual influences and genetic relationships. One can distinguish at least three major strands, which appear to be mostly independent, at least in their earlier stages: Chinese alchemy , centered in China; Indian alchemy , centered on
4949-462: The creation of a divine body (Sanskrit divya-deham ) and immortality while still embodied (Sanskrit jīvan-mukti ). Sanskrit alchemical texts include much material on the manipulation of mercury and sulphur, that are homologized with the semen of the god Śiva and the menstrual blood of the goddess Devī. Some early alchemical writings seem to have their origins in the Kaula tantric schools associated to

While critical of the kind of alchemy he associated with the Egyptian priests and their followers, Zosimos nonetheless saw the tradition's recent past as rooted in

His original system consisted of seven elements, which included the five classical elements ( aether , air , earth , fire , and water ) in addition to two chemical elements representing the metals: sulphur , "the stone which burns", which characterized the principle of combustibility, and mercury , which contained
5353-509: The false promises of transmutation made by pseudo-alchemists. Roman Catholic Inquisitor General Nicholas Eymerich 's Directorium Inquisitorum , written in 1376, associated alchemy with the performance of demonic rituals, which Eymerich differentiated from magic performed in accordance with scripture. This did not, however, lead to any change in the Inquisition's monitoring or prosecution of alchemists. In 1404, Henry IV of England banned

Many schools and businesses employ safety, health, and environmental specialists, such as a Chemical Hygiene Officer (CHO) to develop, manage, and evaluate their CHP. Additionally, third party review is also used to provide an objective "outside view" which provides a fresh look at areas and problems that may be taken for granted or overlooked due to habit. Inspections and audits like also be conducted on

Shortly thereafter, this evolved into eight elements, with the Arabic concept of the three metallic principles: sulphur giving flammability or combustion, mercury giving volatility and stability, and salt giving solidity. The atomic theory of corpuscularianism , where all physical bodies possess an inner and outer layer of minute particles or corpuscles, also has its origins in

The Occupational Safety and Health Administration (OSHA) in the United States, recognizing the unique characteristics of the laboratory workplace, has tailored a standard for occupational exposure to hazardous chemicals in laboratories. This standard is often referred to as
5757-467: The influx of alchemical thought. The 11th-century St Anselm put forth the opinion that faith and rationalism were compatible and encouraged rationalism in a Christian context. In the early 12th century, Peter Abelard followed Anselm's work, laying down the foundation for acceptance of Aristotelian thought before the first works of Aristotle had reached the West. In the early 13th century, Robert Grosseteste used Abelard's methods of analysis and added

In the late ninth and early tenth centuries, the Arabic works attributed to Jābir ibn Hayyān (Latinized as "Geber" or "Geberus") introduced a new approach to alchemy.

Significant impact can be achieved by keeping the opening height as low as possible when working and keeping them closed when not in use. One possibility to help with this, could be to install automatic systems, which close the hoods after an inactivity period of a certain length and turn off the lights as well. So the flow can be regulated better and
6363-747: The mystical aspects of this concept. Alchemy coexisted alongside emerging Christianity . Lactantius believed Hermes Trismegistus had prophesied its birth. St Augustine later affirmed this in the 4th and 5th centuries, but also condemned Trismegistus for idolatry. Examples of Pagan, Christian, and Jewish alchemists can be found during this period. Most of the Greco-Roman alchemists preceding Zosimos are known only by pseudonyms, such as Moses , Isis, Cleopatra , Democritus , and Ostanes . Others authors such as Komarios, and Chymes , we only know through fragments of text. After AD 400, Greek alchemical writers occupied themselves solely in commenting on

Between the time of Bolus and Zosimos, the change took place that transformed this metallurgy into a Hermetic art. Alexandria acted as a melting pot for philosophies of Pythagoreanism , Platonism , Stoicism and Gnosticism which formed
6565-404: The origin of alchemy's character. An important example of alchemy's roots in Greek philosophy, originated by Empedocles and developed by Aristotle, was that all things in the universe were formed from only four elements: earth , air , water , and fire . According to Aristotle, each element had a sphere to which it belonged and to which it would return if left undisturbed. The four elements of

These critiques and regulations centered more around pseudo-alchemical charlatanism than the actual study of alchemy, which continued with an increasingly Christian tone. The 14th century saw

This laboratory was created when Pythagoras conducted an experiment about tones of sound and vibration of string. In the painting of Louis Pasteur by Albert Edelfelt in 1885, Louis Pasteur is shown comparing a note in his left hand with a bottle filled with a solid in his right hand, and not wearing any personal protective equipment . Researching in teams started in

One knows in which miserable state this literature reached us. Collected by Byzantine scientists from the tenth century, the corpus of the Greek alchemists is a cluster of incoherent fragments, going back to all the times since the third century until the end of
6969-614: The prolongation of life. His correspondence with Clement highlighted this, noting the importance of alchemy to the papacy. Like the Greeks before him, Bacon acknowledged the division of alchemy into practical and theoretical spheres. He noted that the theoretical lay outside the scope of Aristotle, the natural philosophers, and all Latin writers of his time. The practical confirmed the theoretical, and Bacon advocated its uses in natural science and medicine. In later European legend, he became an archmage. In particular, along with Albertus Magnus, he

Through ethnographic studies, one finding is that, among the personnel, each class (researchers, administrators...) has a different degree of entitlement, which varies per laboratory. Entitlement can be both formal or informal (meaning it
7272-562: The research community. While many laboratories are used to perform research to find innovative solutions to this global challenge, sustainable working practices in the labs are also contributing factors towards a greener environment. Many labs are already trying to minimize their environmental impact by reducing energy consumption, recycling, and implementing waste sorting processes to ensure correct disposal. Research labs featuring energy-intensive equipment, use up to three to five times more energy per square meter than office areas. Presumably
7373-438: The researchers currently are, as they are not entitled to such information. On the other hand, researchers do have access to this type of information. So a consequence of this social hierarchy is that the Locator discloses various degrees of information, based on the staff member and their rights. The Locator does not want to disclose information that could jeopardize his relationship with the members of staff. The Locator adheres to
7474-479: The rights of each class. Social hierarchy is also related to attitudes towards technologies. This was inferred based on the attitude of various jobs towards their lab badge. Their attitude depended on how that job viewed their badge from a standpoint of utility, (how is the badge useful for my job) morality (what are my morals on privacy, as it relates to being tracked by this badge) and relations (how will I be seen by others if I refuse to wear this badge). For example,
7575-416: The rites of the Egyptian temples. Zosimos of Panopolis asserted that alchemy dated back to Pharaonic Egypt where it was the domain of the priestly class, though there is little to no evidence for his assertion. Alchemical writers used Classical figures from Greek, Roman, and Egyptian mythology to illuminate their works and allegorize alchemical transmutation. These included the pantheon of gods related to

A considerable knowledge of metallurgy has been exhibited in a third-century AD text called Arthashastra which provides ingredients of explosives (Agniyoga) and salts extracted from fertile soils and plant remains (Yavakshara) such as saltpetre/ nitre , perfume making (different qualities of perfumes are mentioned), granulated (refined) Sugar. Buddhist texts from
7777-408: The substances, mark an experimental spirit which is extremely far away from the weird and odd esotericism of the Greek texts. The theory on which Jabir supports his operations is one of clearness and of an impressive unity. More than with the other Arab authors, one notes with him a balance between theoretical teaching and practical teaching, between the 'ilm and the amal . In vain one would seek in
7878-559: The teachings of the personality of Matsyendranath . Other early writings are found in the Jaina medical treatise Kalyāṇakārakam of Ugrāditya, written in South India in the early 9th century. Two famous early Indian alchemical authors were Nāgārjuna Siddha and Nityanātha Siddha. Nāgārjuna Siddha was a Buddhist monk. His book, Rasendramangalam , is an example of Indian alchemy and medicine. Nityanātha Siddha wrote Rasaratnākara , also
7979-488: The technique to purify the human soul ). They believed in the four elements and the four qualities as described above, and they had a strong tradition of cloaking their written ideas in a labyrinth of coded jargon set with traps to mislead the uninitiated. Finally, the alchemists practised their art: they actively experimented with chemicals and made observations and theories about how the universe operated. Their entire philosophy revolved around their belief that man's soul
8080-573: The time included the Turba Philosophorum , and the works of Avicenna and Muhammad ibn Zakariya al-Razi . These brought with them many new words to the European vocabulary for which there was no previous Latin equivalent. Alcohol, carboy , elixir , and athanor are examples. Meanwhile, theologian contemporaries of the translators made strides towards the reconciliation of faith and experimental rationalism, thereby priming Europe for
8181-465: The transmutation of " base metals " (e.g., lead ) into " noble metals " (particularly gold ); the creation of an elixir of immortality ; and the creation of panaceas able to cure any disease. The perfection of the human body and soul was thought to result from the alchemical magnum opus ("Great Work"). The concept of creating the philosophers' stone was variously connected with all of these projects. Islamic and European alchemists developed
8282-406: The two alchemical schools of thought include discrete naming for ingredients and heavy influence from the natural elements. The silk road provided a clear path for the exchange of goods, ideas, ingredients, religion, and many other aspects of life with which alchemy is intertwined. Whereas European alchemy eventually centered on the transmutation of base metals into noble metals, Chinese alchemy had
8383-607: The underlying notion of the lab as a confined space for experts, the term "laboratory" is also increasingly applied to workshop spaces such as Living Labs , Fab Labs , or Hackerspaces , in which people meet to work on societal problems or make prototypes , working collaboratively or sharing resources. This development is inspired by new, participatory approaches to science and innovation and relies on user-centred design methods and concepts like Open innovation or User innovation ,. One distinctive feature of work in Open Labs
8484-646: The university of Edingburgh. Furthermore, several networks have emerged such as Green Your Lab , Towards greener research , the UK-based network LEAN , the Max-Planck-Sustainability network , and national platforms such as green labs austria and green labs NL . More university independent efforts and resources include the Laboratory Efficiency Assessment Framework , the think-tank labos1point5 and
8585-532: The unpublished manuscripts of these titles. A great deal remains to be discovered about Indian alchemical literature. The content of the Sanskrit alchemical corpus has not yet (2014) been adequately integrated into the wider general history of alchemy. After the fall of the Roman Empire , the focus of alchemical development moved to the Islamic World. Much more is known about Islamic alchemy because it
8686-415: The unusual clarity with which they were described. By the end of the 13th century, alchemy had developed into a fairly structured system of belief. Adepts believed in the macrocosm-microcosm theories of Hermes, that is to say, they believed that processes that affect minerals and other substances could have an effect on the human body (for example, if one could learn the secret of purifying gold, one could use
8787-805: The use of gunpowder spread to Japan, the Mongols , the Muslim world, and Europe. Gunpowder was used by the Mongols against the Hungarians in 1241, and in Europe by the 14th century. Chinese alchemy was closely connected to Taoist forms of traditional Chinese medicine , such as Acupuncture and Moxibustion . In the early Song dynasty , followers of this Taoist idea (chiefly the elite and upper class) would ingest mercuric sulfide , which, though tolerable in low levels, led many to suicide. Thinking that this consequential death would lead to freedom and access to
8888-415: The use of complex laboratory equipment from laboratory glassware to electrical devices, and others require more specific or expensive supplies. Laboratory equipment refers to the various tools and equipment used by scientists working in a laboratory. Laboratory equipment is generally used to either perform an experiment or to take measurements and gather data . Larger or more sophisticated equipment
8989-514: The use of metals, minerals, and elixirs in early Chinese medicine. Hong identified three ancient Chinese documents, titled Scripture of Great Clarity, Scripture of the Nine Elixirs , and Scripture of the Golden Liquor, as texts containing fundamental alchemical information. He also described alchemy, along with meditation, as the sole spiritual practices that could allow one to gain immortality or to transcend. In his work Inner Chapters of
9090-417: The use of observation, experimentation, and conclusions when conducting scientific investigations. Grosseteste also did much work to reconcile Platonic and Aristotelian thinking. Through much of the 12th and 13th centuries, alchemical knowledge in Europe remained centered on translations, and new Latin contributions were not made. The efforts of the translators were succeeded by that of the encyclopaedists. In
9191-502: The vocabulary of Greek philosophical schools but did not implement any of its doctrines in a systematic way. Zosimos of Panopolis wrote in the Final Abstinence (also known as the "Final Count"). Zosimos explains that the ancient practice of "tinctures" (the technical Greek name for the alchemical arts) had been taken over by certain "demons" who taught the art only to those who offered them sacrifices. Since Zosimos also called
9292-439: The work of Jabir. From the 9th to 14th centuries, alchemical theories faced criticism from a variety of practical Muslim chemists, including Alkindus , Abū al-Rayhān al-Bīrūnī , Avicenna and Ibn Khaldun . In particular, they wrote refutations against the idea of the transmutation of metals . From the 14th century onwards, many materials and practices originally belonging to Indian alchemy ( Rasayana ) were assimilated in
9393-549: The works of these predecessors. By the middle of the 7th century alchemy was almost an entirely mystical discipline. It was at that time that Khalid Ibn Yazid sparked its migration from Alexandria to the Islamic world, facilitating the translation and preservation of Greek alchemical texts in the 8th and 9th centuries. Greek alchemy was preserved in medieval Byzantine manuscripts after the fall of Egypt , and yet historians have only relatively recently begun to pay attention to
9494-428: The writings of Aristotle and Avicenna, where they concerned the transmutation of metals. From the time shortly after his death through to the 15th century, more than 28 alchemical tracts were misattributed to him, a common practice giving rise to his reputation as an accomplished alchemist. Likewise, alchemical texts have been attributed to Albert's student Thomas Aquinas . Roger Bacon, a Franciscan friar who wrote on
9595-489: Was believed that one would become immortal if an inner god were to be immortalized within them through spiritual fulfilment. Black powder may have been an important invention of Chinese alchemists. It is said that the Chinese invented gunpowder while trying to find a potion for eternal life. Described in 9th-century texts and used in fireworks in China by the 10th century, it was used in cannons by 1290. From China,
9696-419: Was better documented: indeed, most of the earlier writings that have come down through the years were preserved as Arabic translations. The word alchemy itself was derived from the Arabic word al-kīmiyā (الكيمياء). The early Islamic world was a melting pot for alchemy. Platonic and Aristotelian thought, which had already been somewhat appropriated into hermetical science, continued to be assimilated during
9797-440: Was credited with the forging of a brazen head capable of answering its owner's questions. Soon after Bacon, the influential work of Pseudo-Geber (sometimes identified as Paul of Taranto ) appeared. His Summa Perfectionis remained a staple summary of alchemical practice and theory through the medieval and renaissance periods. It was notable for its inclusion of practical chemical operations alongside sulphur-mercury theory, and
9898-563: Was divided within himself after the fall of Adam. By purifying the two parts of man's soul, man could be reunited with God. In the 14th century, alchemy became more accessible to Europeans outside the confines of Latin-speaking churchmen and scholars. Alchemical discourse shifted from scholarly philosophical debate to an exposed social commentary on the alchemists themselves. Dante , Piers Plowman , and Chaucer all painted unflattering pictures of alchemists as thieves and liars. Pope John XXII 's 1317 edict, Spondent quas non-exhibent forbade
9999-419: Was externally cold and dry, while gold was hot and moist. Thus, Jabir theorized, by rearranging the qualities of one metal, a different metal would result. By this reasoning, the search for the philosopher's stone was introduced to Western alchemy. Jabir developed an elaborate numerology whereby the root letters of a substance's name in Arabic, when treated with various transformations, held correspondences to
10100-757: Was historically practised in China , India , the Muslim world , and Europe . In its Western form, alchemy is first attested in a number of pseudepigraphical texts written in Greco-Roman Egypt during the first few centuries AD. Greek-speaking alchemists often referred to their craft as "the Art" (τέχνη) or "Knowledge" (ἐπιστήμη), and it was often characterised as mystic (μυστική), sacred (ἱɛρά), or divine (θɛíα). Alchemists attempted to purify, mature, and perfect certain materials. Common aims were chrysopoeia ,
10201-529: Was itself adopted from the Arabic word al-kīmiyā ( الكيمياء ). The Arabic al-kīmiyā in turn was a borrowing of the Late Greek term khēmeía ( χημεία ), also spelled khumeia ( χυμεία ) and khēmía ( χημία ), with al- being the Arabic definite article 'the'. Together this association can be interpreted as 'the process of transmutation by which to fuse or reunite with the divine or original form'. Several etymologies have been proposed for
