From the Kathak Branch of the Wedas (Katha-Upanishad)

 Death said: 'God made sense turn outward, man therefore looks outward, not into himself. Now and again a daring soul, desiring immortality, has looked back and found himself. T h e ignorant man runs after pleasure, sinks into the entanglements of death; but the wise man, seeking the undying, does not run among things that die. 'He through whom we see, taste, smell, feel, hear, enjoy, knows everything. He is that Self. 'The wise man by meditating upon the self-dependent, all-pervading Self, understands waking and sleeping and goes beyond sorrow.
