Sam and Joe discuss Verse 4 of the Tao Te Ching:

The Way is empty, yet inexhaustible,

Like an abyss!

It seems to be the origin of all things.

It dulls the sharpness,

Unties the knots,

Dims the light,

Becomes one with the dust.

Deeply hidden, as if it only might exist.

I do not know whose child it is.

It seems to precede the ancestor of all.
