Patanjali

Patanjali (, , ) also called Gonardiya or Gonikaputra, was a Hindu author, mystic and philosopher. Estimates based on analysis of his works suggests that he may have lived between the 2nd century BCE and the 4th century CE. Patanjali is regarded as an avatar of Adi Sesha.

He is believed to be an author and compiler of a number of Sanskrit works. The greatest of these are the ''Yoga Sutras'', a classical yoga text. There is speculation as to whether the sage Patañjali is the author of all the works attributed to him, as there are a number of known historical authors of the same name. A great deal of scholarship has been devoted over the 20th century to the issue of the historicity or identity of this author or these authors. Provided by Wikipedia
