Thus one should know oneself to be of the nature of Existence-Consciousness-Bliss[Sat-Chit-Ananda].
Adi ShankaraLike the appearance of silver in mother of pearl, the world seems real until the Self, the underlying reality, is realized.
Adi ShankaraYou never identify yourself with the shadows cast by your body, or with its reflection, or with the body you see in a dream or in your imagination. Therefore you should not identify yourself with this living body either.
Adi ShankaraJust as a stone, a tree, a straw, grain, a mat, a cloth, a pot, and so on, when burned, are reduced to earth (from which they came), so the body and its sense organs, on being burned in the fire of Knowledge, become Knowledge and are absorbed in Brahman, like darkness in the light of the sun.
