There is no other duty for man except meditation on the self. Dismissing all else, one should establish oneself in the self. There remains nothing to be done or attained when the self is experienced. For that Brahman the immortal is before, behind, to the right and to the left and stretched forth above and below.
Brahman is all this. The real alone is an enduring being and this real is experienced through meditation coupled with knowledge. Whatever a man of purified mind makes clear in his mind, and whatever desires he desires, that he gets and that he fulfills. One should therefore have pure and perfect resolves.
The supreme self is experienced in the fourth state of consciousness.It is neither this nor that it has no quality in particular and yet it is everything. It is peaceful, blessed and nondual. It is the cessation of all phenomena. It is the atman that should be known and realised. That is the purpose of life. The liberated sage experiences that he is everything the tree, the mountain, the sun. He is the food and the eater of the food. He is the knower, the knowledge and the known, in one. He is the whole universe in himself.
Bliss is the ultimate nature of reality from bliss all this comes forth. All the bliss of the world is only a shadow of selfbliss. The self is the source of all bliss it is everything all knowledge and all bliss. All this is based on consciousness and is guided by consciousness. Consciousness is Brahman. I am Brahman. That thou art. This self is Brahman. Only the infinite is bliss. There one sees nothing else, hears nothing else, understands nothing else. That is the infinite fullness.
The self is an ocean without a shore and a surface. It is merely existence, consciousness and bliss. When there is duality one can speak to the other, but when everything is but one's own self then who can speak to whom? Who can see whom?
Atman is pure consciousness it is the unchanging witness. It is realized within your heart as existence, knowledge, bliss absolute. Realise this atman within the temple of your own heart and enjoy immortal bliss.
