"We form part of what the Alchemists call the Anima Mundi, the soul of the world; the truth is that if the Anima Mundi were merely to keep dividing, it would keep growing, but it would also become gradually weaker. That is why, as well as dividing into two, we also find ourselves. And the process of finding ourselves is called love. Because when a soul divides, it always divides into a male part and a female part."
