To love in the sense of passion-love is the contrary of to live. It is an impoverishment of one's being, an askesis without sequel, an inability to enjoy the present without imagining it as absent, a never-ending flight from possession.
What stirs lyrical poets to their finest flights is neither the delight of the senses nor the fruitful contentment of the settled couple; not the satisfaction of love, but its passion. And passion means suffering.
One possessed a thousand and three women (in Spain alone), the other only one. But it is multiplicity that is impoverished, whilethe entire world is concentrated in a single being infinitely possessed. Tristan no longer needs the world--because he loves! While Don Juan, always loved, cannot love in return. Hence his anguish and his frenzied course.
