Baba Ramdev is a popular Hindu leader. He is widely respected and celebrated for his teachings on yoga shastra. He is a tireless teacher to millions of people. He has rendered incomparable service to his followers in India, and — with the power of the internet — around the world. No one can take away the significance of his achievements in bringing understanding and empowerment to his followers in their private and social lives.
No one except Baba Ramdev himself, that is.
I think that the greatest enemy that Baba Ramdev faces is himself, as sometimes happens with people with extraordinary talent. They are victims of their own successes, and the knife sticking out of their backs is often one that they themselves hand to their attackers.
