Love is the great intangible. In our nightmares, we can create beasts out of pure emotion. Hate stalks the streets with dripping fangs, fear flies down narrow alleyways on leather wings, and jealousy spins sticky webs across the sky. In daydreams, we can maneuver with poise, foiling an opponent, scoring high on fields of glory while crowds cheer, cutting fast to the heart of an adventure. But what dream state is love? Frantic and serene, vigilant and calm, wrung-out and fortified, explosive and sedate –love commands a vast army of moods. Hoping for victory, limping from the latest skirmish, lovers enter the arena once again. Sitting still, we are as daring as gladiators.
