Jnana is given neither from outside nor from another person. It can be realised by each and everyone in his own Heart. The jnana Guru of everyone is only the Supreme Self that is always revealing its own truth in every Heart through the being-conciousness 'I am, I am.' The granting of true knowledge by him is initiation into jnana. The grace of the Guru is only that Self-awareness that is one's own true nature. It is the inner conciousness by which he is unceasingly revealing his existence. This divine upadesa is always going on naturally in everyone.
Ramana MaharshiThe Self alone exists. When you try to trace the ego, which is the basis of the perception of the world and everything else, you find the ego does not exist at all and neither does all this creation that you see.
