This is one of the first books written by a member of AMAYE on a sutra-by-sutra explanantion of Patainjali's Yoga Sutram. Ac. Candreshvaranandaji has been kind to offer his assistance to Keshava in this venture. We hope that the book will be translated into English also for wider audience. It appears that the commentary has been written in light of Ananda Sutram. The book is available from Ananda Marga Publications in Taiwan.
