When a room is dark you need a lamp to light it, but when the sun rises there is no need for a lamp; objects are seen without one. And to see the sun itself no lamp is needed because it is self-luminous. Similarly with the mind. The reflected light of the mind is necessary to perceive objects, but to see the heart it is enough for the mind to be turned towards it. Then the mind loses itself and the Heart shines forth. The mind turned inward is the Self; turned outward it becomes the Ego and all the world.
Sri Ramana Maharshi
