We cannot expect that millions are practicing real yoga just because millions of people claim to be doing yoga all over the globe. What has spread all over the world is not yoga. It is not even non-yoga; it is un-yoga.
If you are looking for a whale you cannot search for a whale in a pond. You must go to deep waters.
What has spread all over the world is not yoga. It is not even non-yoga; it is un-yoga.
