After studying Sanskrit for 3 years now, I can say that all this GREAT BABA’s are just ordinary people like you and me. They have spend their half of the life in learning the Vedas and here they are. If I spend my half of the life in learning "SASTRA" & "SUTRA" believe me I will be "Nishit Baba" from Nishit.
If anybody wants to really learn who we are, what we are then remember you need to have somebody with a highly qualified Upanishads dictator who can teach you and that also if you are lucky enough so its hardly impossible that "Nirmal Baba", "Ramdev Baba" or "Avdhoot Baba" is really going to change your life.
Remember what the Great Hitler said " If you repeat the incorrect sentence(false) 100 times then that incorrect sentence becomes true and people will believe it. No wonder why all this " Om Shanti Om Institute" & others are leading to the success because of us.
Basic simple thing : If you really want to know who you are or if you really want to chage your life or even you need happiness then PLEASE....Go to temple.....You will get all you need but by going to this Baba will not help you out.
Good luck
