" In profound meditation, they found, when consciousness is so acutely focused that it is utterly withdrawn from the body and mind, it enters a kind of singularity in which the sense of a separate ego disappears. In this state, the supreme climax of meditation, the seers discovered a core of consciousness beyond time and change. They called it simply Atman, the Self. "
