A frog in a well cannot conceive of the ocean.

A battering ram can knock down a city wall, but it cannot stop a hole. Different things have different uses.

All men know the use of the useful, but nobody knows the use of the useless. Where can I find a man who has forgotten words so that I can have a word with him?

Compare birth with death, compare death with life; compare what is possible with what is not possible and compare what is not possible with what is possible; because there is, there is not, and because there is not, there is.

Let your mind wander in the pure and simple. Be one with the infinite. Let all things take their course.

When an archer is shooting for nothing, he has all his skill. If he shoots for a brass buckle, he is already nervous. If he shoots for a prize of gold, he goes blind or sees two targets - He is out of his mind! His skill has not changed. But the prize divides him. He cares. He thinks more of winning than of shooting- And the need to win drains him of power.

Sound intelligence promises victory in every battle.
