I picked Aurobindo's The Synthesis of Yoga at the library one day in about 1976. It was way over my head. Maybe about 10 years ago I cam a cross it again and started from page one reading very slowly. I ended up reading all 900 or so pages though it took a few years, Best thing I ever did. It was like a prolonged meditation. So then I read The life Divine. I have to say that Sri Aurobindo had been my man to go to for in depth understanding of reality. Finding him has been like finding a hidden treasure.
Is anyone else here interested in discussing his views on yoga?
