"(...) long ago, humans were composed of two people stuck back-to-back, with two faces and eight limbs. Male-male humans came from the Sun, female-female humans from the Earth and male-female humans from the Moon. The gods, out of jealousy, split them in half. Now, throughout our lives, we are always trying to find our "other half", and sexual intercourse is the only means we have to put the two halves back together; this desire to be one person again is what we call "love". However, it is impossible to fully rejoin two people because it is our souls and not our bodies that most desire to be reunited."
