I still believe that man, not having been given the power of creation, does not posses the right of destroying the meanest creature that lives. The perogative of destruction belongs solely to the Creator of all that lives.
Isn't it really quite extraordinary to see that, since man took his first step, no one has asked himself why he walks, how he walks, if he has ever walked, if he could walk better, what he achieves in walking .. questions that are tied to all the philosophical, psychological, and political systems which preoccupy the world.

Somebody insults you and you feel anger. Don't miss this opportunity; try to understand why, why this anger. And don't make it a philosophical thing. Don't go to the library to consult about anger. Anger is happening to you -- it is an experience, a live experience. Focus your whole attention on it and try to understand why it is happening to you. It is not a philosophical problem. No Freud is to be consulted about it. There is no need! It is just foolish to consult somebody else while anger is happening to you. You can touch it. You can taste it. You will be burned by it.
