On revient toujours a son premier amour." It sounds like a cynicism to-day. As if we really meant: "On ne revient jamais a son premier amour." But as a matter of fact, a man never leaves his first love, once the love is established. He may leave his first attempt at love. Once a man establishes a full dynamic communication at the deeper and higher centers, with a woman, this can never be broken. But sex in the head breaks down, and half circuits break down. Once the full circuit is established, however, this can never break.
