Loud speech, profusion of words, and possessing skillfulness in expounding scriptures are merely for the enjoyment of the learned. They do not lead to liberation.
Adi ShankaraThe witness of the three states of consciousness [waking, dream and deep sleep] and of the nature of Existence-Consciousness-Bliss is the Self
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.
