The Chariot!

Know the Self as lord of the chariot,
The body as the chariot itself,
The discriminating intellect as
The Charioteer, and the mind as reins.

The senses, say the wise, are the horses;
Selfish desires are the roads they travel.
When the Self is confused with the body,
Mind, and senses, they point out, he seems
To enjoy pleasure and suffer sorrow.

When a person lacks discrimination
And his mind is undisciplined, the senses
Run hither and thither like wild horses.
But they obey the rein like trained horses
When one has discrimination and
Has made the mind one-pointed...

Knowing the senses to be separate
From the Self, and the sense experience
To be fleeting, the wise grieve no more.

Above the senses is the mind, above
The mind is the intellect, above that
Is the ego, and above the ego
Is the unmanifested Cause...

~ Katha Upanishad
