A guide that leaves no tracks;
A voice with no echo;
An accountant without entries
A door with no lock,
Yet no one seems able to open it.
A binding that requires no knots,
Yet no one can loosen it.

Therefore the sage abandons no one.
He supports all things
And abandons nothing.

This is called "being the light."

What is a real man?
A teacher of a boy.
What is a boy?
A real man's charge.
If the teacher is not respected,
And the student not called to manhood,
All kinds of stupid shit will go down.
This is the crux of mystery.
