Scholars have rejected his theories in entirety and his writings have been heavily criticized. Acute misrepresentation of facts coupled with wrong observations, extremely flexible and often self-contradictory analysis, cherry picking of data and forwarding of easily disprovable hypotheses have been located. His understanding of linguistics and subsequent assertion have been challenged. Romila Thapar calls Kak an amateur historian whose views on

Witzel concludes that
1287-473: The study of Vedic cosmology from an empirical astronomical/mathematical viewpoint". Klostermaier's books have been heavily criticized for offering pro-Hindu views that have little currency in scholarship.

Kak wrote
