Beyond peace is bliss. Peace is a negative state, being merely the absence of the waves of pleasure, pain, and indifference; and so after a little while, the meditator is attracted once more by the desire to experience the waves of motion. But as meditative peace deepens into calmness and the ultimate positive state of bliss, the meditator experiences a joy that is ever new and all satisfying." -- Paramahansa Yogananda.
