Ira Schepetin is an scholar of Indian traditional philosophies and in particular Vedanta. I had the pleasure to ask him a couple of questions about the relationship of Yoga and indian traditional philosophies during last season in India.
Of course, he didn't have time to cover the topic in depth but he gives some glimpses in this conversation which can be useful. He mentions the differences between Vedanta, Yoga (the philosophy) and Buddhism in several fundamental aspects.
There are several of Ira's speeches in youtube like this one https://www.youtube.com/watch?v=usu_cLGXLg4
I really like listening to Ira and I hope next year I get another opportunity to record another chapter of the podcast.
