' Prashna Upanishad '...

It is the Self who sees, hears, smells, touches, And tastes, who thinks, acts, and is pure consciousness. The Self is Brahman, changeless and supreme. ........................................ Those who know the supreme Self as formless, Without shadow, without impurity, Know all, gentle friend, and live in all. Those who know the Self, the seat of consciousness, In whom the breath and all the senses live, Know all, gentle friend, and live in all. ........................................ -Prashna Upanishad Excerpted from The Upanishads, translated by Eknath Easwaran
