Empty of all doctrines,
The Tao is wisdom eternally inexhaustible.
Fathomless for the mere intellect,
The Tao is the law wherewith all things come into being.
It blunts the edges of the intellect,
Untangles the knots of the mind,
Softens the glare of thinking,
And settles the dust of thought.
Transparent yet invisible,
The Tao exists like deep pellucid water.
Its origin is unknown,
For it existed before Heaven and Earth
