The Yoga Sutras Of Patanjali

Patanjali, also called Gonardiya, or Gonikaputra, (flourished 2nd century BCE or 5th century CE), author or one of the authors of two great Hindu classics: the first, Yoga-sutras, a categorization of Yogic thought arranged in four volumes with the titles "Psychic Power," "Practice of Yoga," "Samadhi" (state of profound contemplation of the Absolute), and "Kaivalya" (separateness); and the second, the Mahabhashya ("Great Commentary"), which is both a defense of the grammarian Panini against his chief critic and detractor Katyayana and a refutation of some of Panini's aphorisms.
