People blame philospher Rene Descartes for the modern idea that spirit and body are two separate and antagonistic entities. I don't. I think making this division is an age-old trap. It takes work to see clearly that you need your physical senses to be a spiritual person, and that you need a spiritual acceptance of life's goodness to be profoundly sensual and sexual.
When you finally get body and spirit together--Renaissance writers said you need to be a person of soul to do this--you will discover greater joy in lovemaking. It makes sense: If you are a whole person made up of body, soul, and spirit,when you make love with only your body, you're getting only one third of the sex. Spirit and soul like sex, too, and they add immensely to the pleasure.
