The way that can be mapped
is not the eternal Way.
The name that can be spoken
is not the eternal Name.
The nameless is the womb of Heaven and Earth.
- Tao Te Ching, Chapter 1
The supreme good is like water,
which nourishes all of creation
without trying to compete with it.
It flows into humble places.
Thus it is like the Way.
- Tao Te Ching, Chapter 8
The main Taoist text (and possibly the book that has been translated more than any other) is the Tao Te Ching, written by Lao Tsu.
