The Self is here and now, it is the only Reality. There is nothing else.

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.

Doubts arise because of an absence of surrender.

When one makes the mind stick to one thought, the mind becomes rock-steady and the energy is conserved.

Is it the world that says I am real, or is it you?

It is enough that one surrenders oneself. Surrender is giving oneself up to the original cause of one's being. Do not delude yourself by imagining this source to be some God outside you. One's source is within oneself. Give yourself up to it. That means that you should seek the source and merge in it.

The self cannot be found in books. You have to find it for yourself, within yourself.
