@traciyork I know all these by self practice as a member of Guru Ramdev's Patanjali Yogapeeth. Here is the picture of the Patanjali where I was in the last month only. I am planning to write a book on Yoga and its benefits. Thanks for your suggestion though!
Note, I joined this community for my interest in this topic because @eco-alex alex is an expert in Yoga.
I took this picture during my 3 day's session there besides we the Indians are expert in yoga and it postures.
