Do you not know how it is with love? First comes delight: then pain: then fruit. And then there is joy of the fruit, but that is different again from the first delight. And mortal lovers must not try to remain at the first step: for lasting passion is the dream of a harlot and from it we wake in despair. You must not try to keep the raptures: they have done their work. Manna kept, is worms.
