True love is that which ennobles the personality, fortifies the heart, and sanctifies the existence.

To be misunderstood even by those whom one loves is the cross and bitterness of life. It is the secret of that sad and melancholy smile on the lips of great men which so few understand; it is the cruelest trial reserved for self-devotion; it is what must have oftenest wrung the heart of the Son of man; and if God could suffer, it would be the wound we should be forever inflicting upon Him. He also - He above all - is the great misunderstood, the least comprehended.

The more a man loves, the more he suffers. The sum of possible grief for each soul is in proportion to its degree of perfection.
