What i am...? this is very simple that i am a" spirit". spirit live in the body and doing everything by the body of the"jieva". but jieva has two main power like "buddhi" and "man". buddhi take decision and man create requirement but when jieva act then spirit alert that person that what is correct..........? if correct then do otherwise don't do. if go with this logic then you are successfull in your life.
If we are behave like this then we have no chance of mistake and result will be good.life will meaningfull. so please try to that always.
