A man’s body is the most perfect thing that the Godhead created for him. Man’s body is the most perfect form that the Gods developed. It’s an instrument through which man’s soul looks out into the world. The human body is equipped in a wonderful way. Man’s body is supposed to be a sacred temple for his soul. But the soul is not yet perfected. It’s just beginning to develop. Man’s body makes no mistakes; it’s the imperfect soul that’s constantly making them. Passions, desires, and drives live in it, and it uses the body to satisfy these desires.
But just as there are senses in man’s body through which the soul looks out into the world, so organs will also gradually develop in the soul that will make it ever more perfect. Such organs are already developing in the soul.
