The Yoga Sutra classes you taught were truly wonderful! It's the first time I have had the opportunity to study from someone who thoroughly understands the Sutras. Although, your class has generated many topics in the Sutras that I want to study, there is one topic that I want to pursue first. You asked me if I knew about the mistakes in Buddhist philosophy --- which I did not. Can you suggest a reference or web site where I could learn more about this topic?
