Who makes the mind think?

Who fills my body with vitality?

Who causes my tongue to speak?  Who is that

Invisible one who sees through my eyes

and hears through my ears?

The Teacher

The Self is the ear of the ear,

The eye of the eye, the mind of the mind,

The word of the word, and the life of life.

Rising above the senses and the mind

And renouncing separate existence,

The wise realize the deathless Self.

Him our eyes cannot see, nor words express;

He cannot be grasped even by the mind.

We do not know, we cannot understand,

Because he is different from the known

And he is different from the unknown.

Thus have we heard from the illumined ones.

That which makes the tongue speak but cannot be 

Spoken by the tongue, know that as the Self.

This Self is not someone other than you.

That which makes the mind think but cannot be

Thought by the mind, that is the Self indeed.

This Self is not someone other than you.

That which makes the eye see but cannot be 

Seen by the eye, that is the Self indeed.

This Self is not someone other than you.

That which makes the ear hear but cannot be 

Heard by the ear, that is the Self indeed.

This Self is not someone other than you.

That which makes you draw breath but cannot be

Drawn by your breath, that is the Self indeed.

This Self is not someone other than you.

~ The Kena Upanishad

translated and introduced by Eknath Easwaran

There is a Sufi story about a seeker who calls on Allah day in and day out for years and finally throws himself down and sobs,  "How long have I been calling and you do not answer!"  Then he hears a voice:  "Who do you think has been making you call me?"

Kena, in the title means "by whom?" - that is, impelled by whom do all the motions stir?  Or in Shankara's brilliant paraphrase, "By whose mere presence does that desire arise which moves the universe?"
