As you may recall, I am reading three different version of the Yoga Sutras - the first being T.K.V. Desikachar's translation and commentary, Swami Satchidananda's translation and commentary, as Edwin Bryant's tome. I generally read on sutra per day, and read it from each of the books. Often Edwin's version will have a lengthy discussion as well which is really educational.
Long story short, it has been taking a while to read through the Sutras but I have finally reached the last and final chapter Kaivalya Pada, or as one of them translated it Absolute Independence.
Progress is progress but I'd probably be making more of that if I were only reading one, but more importantly weren't taking a Yoga Sutra's workshop with Dr. Bryant Which I have now extended to include his study group, or Svādhyāya-śālā on Friday nights. This class is currently studyig the Sāṃkhya Kārikā. Dr. Bryant says on his website:
This is the primary text of the Sāṃkhya School – it plays the same canonical role for Sāṃkhya as the Yoga Sūtras play for Yoga. We can note that actually Yoga and Sāṃkhya were originally one system (as the Gītā also notes: V.3-4), with Sāṃkhya occupying itself primarily with the metaphysics of prakṛti, and Yoga with the practices leading to puruṣa.
If you are interested feel free to come on Friday evening's at 6pm. Check his side for the specific dates.
