Patanjali

Patañjali was a sage in India, thought to be the author of a number of Sanskrit works. The greatest of these are the Yoga Sutras, a classical yoga text. There is doubt 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 last century to the issue of the historicity or identity of this author or these authors.Amongst the more important authors called Patañjali are:
The author of the Mahābhāṣya, an ancient treatise on Sanskrit grammar and linguistics, based on the Aṣṭādhyāyī of Pāṇini. This Patañjali’s life is dated to mid 2nd century BCE by both Western and Indian scholars. This text was titled as a bhasya or “commentary” on Kātyāyana-Pāṇini’s work by Patanjali, but is so revered in the Indian traditions that it is widely known simply as Mahā-bhasya or “Great commentary”.
