This is the great lesson that we are here to learn through myriads of births and heavens and hells - that there is nothing to be asked for, desired for, beyond one's spiritual Self (atman).
Swami VivekanandaThe difference between God and the devil is in nothing except in unselfishness and selfishness. The devil knows as much as God, is as powerful as God; only he has no holiness that makes him a devil. Apply the same idea to the modern world: excess of knowledge and power, without holiness, makes human beings devils.
