Then comes meditation. That is the highest state. ... When [the mind] is doubtful that is not its great state. Its great state is meditation. It looks upon things and sees things, not identifying itself with anything else. As long as I feel pain, I have identified myself with the body. When I feel joy or pleasure, I have identified myself with the body. But the high state will look with the same pleasure or blissfulness upon pleasure or upon pain. ... Every meditation is direct superconsciousness. In perfect concentration the soul becomes actually free from the bonds of the gross body and knows itself as it is. Whatever one wants, that comes to him. Power and knowledge are already there. The soul identifies itself with that which is powerless matter and thus weeps. It identifies itself with mortal shapes. ... But if that free soul wants to exercise any power, it will have it. If it does not, it does not come. He who has known God has become God. There is nothing impossible to such a free soul. No more birth and death for him. He is free for ever.
