27th Verse of the Tao Te Ching
A knower of the truth
travels without leaving a trace,
speaks without causing harm,
gives without keeping an account.
The door he shuts, although having no lock,
cannot be opened.
The knot he ties, though using no cord,
cannot be undone.
Be wise and help all beings impartially,
abandoning none.
Waste no opportunities.
This is called following the light.
What is a good man but a bad man's teacher?
What is bad man but a good man's job?
If the teacher is not respected
and the student not cared for,
confusion will arise, however clever one is.
This is the great secret.
