The teaching of the Tao Te Ching is moral in the deepest sense. Unencumbered by any concept of sin, the Master doesn’t see evil as a force to resist, but simply as an opaqueness, a state of self-absorption which is in disharmony with the universal process, so that, as with a dirty window, the light can’t shine through. This freedom from moral categories allows him his great compassion for the wicked and the selfish.

  Thus the Master is available to all people
  and doesn’t reject anyone.
  He is ready to use all situations
  and doesn’t waste anything.
  This is called embodying the light.

  What is a good man but a bad man’s teacher?
  What is a bad man but a good man’s job?
  If you don’t understand this, you will get lost,
  however intelligent you are.
  It is the great secret.
