Kena Upanishad: From: Sama Veda

Sense organs like mind, eyes, ear, etc, be,

Totally powerless by themselves certainly;

They require power to function in actuality,

That source of power Brahman or Self be;

It Supreme Reality on which all rests surely,

It the hub of wheel - causing rolling to be;

Our wisdom lies in realizing that Power truly,

This sense world is not real - but a dream be;
