To perceive things in the germ is intelligence

For all things difficult to acquire, the intelligent man works with perseverance.

If you would take, you must first give, this is the beginning of intelligence.

All difficult things have their origin in that which is easy, and great things in that which is small.

The Tao that can be told is not the eternal Tao; the name that can be named is not the eternal name. The Nameless is the origin of Heaven and Earth; the Named is the mother of all things.

If you do not change direction, you may end up where you are heading.
