Anyone who really wanted to get rid of suffering would have to get rid of love before anything else, because there can be no love without suffering, because it always demands an element of self-sacrifice, because, given temperamental differences and the drama of situations, it will always bring with it renunciation and pain.

When we know that the way of love–this exodus, this going out of oneself–is the true way by which man becomes human, then we also understand that suffering is the process through which we mature. Anyone who has inwardly accepted suffering becomes more mature and more understanding of others, becomes more human. Anyone who has consistently avoided suffering does not understand other people; he becomes hard and selfish.
