Tao Te Ching 35

To him who holds in his hands the Great Image of the invisible Tao, the whole world repairs. Men resort to him, and receive no hurt, but find rest, peace, and the feeling of ease.

Music and dainties will make the passing guest stop for a time. But though the Tao as it comes from the mouth, seems insipid and has no flavor, though it seems not worth being looked at or listened to, the use of it is inexhaustible.
