This post is inspired by Claudia's January 16th post, "How come there are no Indians in the Mysore Shala?"
I have my own theories as to the answer to this question, but I'll keep them to myself, since I don't feel I'm in a position to say anything really illuminating about this (This is rare; it is not often that I keep my views to myself...). Rather, I'll share David Williams' thoughts on this. In a 2002 interview with Guy Donahaye, Williams remarked that, "I believe more people outside of India now are practicing Yoga than inside of India."
When Donahaye went on to ask him why this is so, Williams replied,
"A lot of people in India didn't have the leisure time to do it, for one thing. A huge amount of the population works for enough food to feed themselves and their family that day and they are working from dawn to dark. Also, at least with this system of yoga, it was only taught to brahmins up till we sort of released it to the rest of the world and prior to, say, the 1960s, yoga was kept pretty much a secret. The guru taught the disciple and there was a lineage and, before mass communication, one person would learn one yoga system in their life, if they got introduced to Yoga. Now all of that has been blown wide open with mass communication and videos and all of that."
I just thought I'd share this, since you might find this to be of interest.
