Every beautiful action, thought or speech is derived from the effacing of self, or ego. For instance, every manner of courtesy comes from holding the reins of the ego. Beauty of speech always depends on the same effacement of the self, and so it is with thought. As soon as the ego expresses itself without control it hurts the ego of another person. The tendency in the lower creatures to fight is caused only by the ego, and man has this tendency no less than they, but rather more. It is this tendency which brings about disturbances in the life of individuals and in the multitude. The family feuds in ancient times, and now wars, all come from the same source, the ego.
