Kena (Upanishad) Part First
1By whom commanded and directed does the mind go towards its objects? Commanded by whom does the life-force, the first (cause), move? At whose will do men utter speech? What power directs the eye and the ear?
2It is the ear of the ear, the mind of the mind, the speech of the speech, the life of the life, the eye of the eye. The wise, freed (from the senses and from mortal desires), after leaving this world, become immortal.
3There the eye does not go, nor speech, nor mind. We do not know That; we do not understand how It can be taught. It is distinct from the known and also It is beyond the unknown. Thus we have heard from the ancient (teachers) who told us about It.
4That which speech does not illumine, but which illumines speech: know that alone to be the Brahman (the Supreme Being), not this which people worship here.
5That which cannot be thought by mind, but by which, they say, mind is able to think: know that alone to be the Brahman, not this which people worship here.
6That which is not seen by the eye, but by which the eye is able to see: know that alone to be the Brahman, not this which people worship here.
7That which cannot be heard by the ear, but by which the ear is able to hear: know that alone to be Brahman, not this which people worship here.
8That which none breathes with the breath, but by which breath is in-breathed: know that alone to be the Brahman, not this which people worship here.
