Joy in the real sense of the word is known to the lover alone. The loveless know it by name, not in reality. It is like the difference between a rock and man. Man, with all life's struggles and difficulties, would rather live as a man than become a rock, which no struggle or difficulty can ever touch; for even with struggles and difficulties the joy of living is immense. With all the pains and sorrows that the lover has to meet with in love, his joy in love is unimaginable, for love is life, and its lack is death.
