Life comes from the earth and life returns to the earth.

That knowledge which stops at what it does not know, is the highest knowledge.

When the shoe fits, the foot is forgotten. When the belt fits, the belly is forgotten. When the heart is right, "for" and "against" are forgotten. No drives, no compulsions, no needs, no attractions: Then your affairs are under control. You are a free man.

Great knowledge sees all in one. Small knowledge breaks down into the many.

Sound intelligence promises victory in every battle.

Calculate what man knows and it cannot compare to what he doesn't know. Calculate the time he is alive and it cannot compare to the time before he was born. Yet man takes something so small and tries to exhaust the dimensions of something so large!

If the Tao could be served up, everyone would serve it up to their lords. If the Tao could be offered, there is no one who would not offer it to their parents. If the Tao could be spoken of, there is no one in the world who would not speak of it to their brothers and sisters. if the Tao could be passed on, there is no one who would not pass it on to their heirs. However, it obviously cannot be so and the reason is as follows. If there is no true centre within to receive it, it cannot remain;if there is no true direction outside to guide it,it cannot be received.
