When you equate yourself with a body, you will always experience depression,” says the Course. Equating another person with a body will bring up the same anxiety. One of the ways the body can be used to manufacture depression is through loveless sex. Our sexual impulses become canvases onto which we extend our love or project our fear. When sex is of the Holy Spirit, it is a deepening of communication. When it is of the ego, it is a substitute for communication. The Holy Spirit uses sex to heal us; the ego uses it to wound us. Sometimes we have thought that sex with another person would cement the bond between us, and instead it turned out to manufacture more illusion and anxiety than there was before. It is only when sex is a vehicle for spiritual communion that it is truly loving, that it joins us to another person. Then it is a sacred act.
