"You must have absolute faith in your own perceptions of truth. Never act in haste or hurry; be deliberated in everything; wait until you know the true way."

When a man has fulfilled all four of these requisites-to be wide awake, to have fear, respect, and absolute assurance-there are no mistakes for which he will have to account; under such conditions his actions lose the blundering quality of the acts of a fool. If such a man fails, or suffers a defeat, he will have lost only a battle, and there will be no pitiful regrets over that.
