It is the opening of the communication with external life which makes man wider. Then he does not say of his friend: "This is my friend, I love him", but he says: "This is myself, I love him." That is the time when he can say that he has arrived at the realization of love. As long as he says: "I feel sympathy with him because he is my friend", his sympathy has not yet fully awakened. The real awakening of his sympathy is on that day when he sees his friend and says "this is myself." Then the sympathy is awakened, then there is the communication within one's self.
