Do Anna Hazare a stubborn person ? even Swami Agnivesh lashes out.........?

Yes. Anna Hazare is crossing the limits now. I urge the central government to treat him the same way they treat the joker Ramdev !!!!!

Do you know Swami agnivesh ?

I don't know him personally, but like all informed Aryas, I have read a good deal about him, his views and his activities. Some information can be found here: Personally, I think he is more concerned with his own political career than actually doing the work of Krinvanto Viswam Aryam as set before us by Swamiji.
