Self-realization can be learned only in one way, in three grades. For this one needs no books, no study; one can learn it only from life. If a least little insult makes one vexed, and a least little praise makes one feel so flattered - if that is one's condition - how can one call oneself God-conscious? The self-realized ones are those to whom insult or praise, rise or fail are indifferent. They will deserve to be called so whom neither sin nor virtue can touch. Heaven and hell are the playgrounds of their imagination. They are, although on earth, yet above the earth.
