This was so interesting and an insight into why your teachings feel so good in my body and mind.  Interesting that 30 years or so ago (😱) when I moved from a studio practice to mainly a home practice, Nevine Michaan's VHS "Katonah Yoga" was one of about 10 different videos I owned and practiced over and over!  Of course, I donated it to Goodwill long ago, when DVDs came around...I hadn't even thought about that VHS until I watched your talk today.  I do recall that it was my introduction to "legs up the wall" 🥰
