A good door needs no lock, still it can't be opened.

How can a man's life keep it's course If he will not let it flow, Those who flow as life flows know They need no other force: They feel no wear, they feel no tear, They need no mending, no repair.

He who gains a victory over other men is strong; but he who gains a victory over himself is all powerful.

The sage has no concern for himself, but makes the concerns of others his own.

Those who are unswerving have resolve

Who is unhappy with little, won't be with much; who doesn't appreciate the small won't be able to take care of the large; who doesn't have enough with enough is at the margin or virtue, for the physical body lives from one day to another and if it gets what it really needs, there will be time for meditation, as long as if we try to give it everything it desires, endless will be the task.

There is a thing inherent and natural which existed before heaven and earth. Motionless and fathomless, It stands alone and never changes; It pervades everywhere and never becomes exhausted. It may be regarded as the Mother of the Universe. I do not know its name. If I am forced to give It a name, I call it Tao, and I name it as supreme.
