In the sexual act, we want to escape the sense of being imprisoned by skin and separated from the rest of the universe. Often, however, this desire remains quite unconscious, and then sex is engaged in as a mere diversion from the concerns and stresses of daily life. Our contact is only skin deep, and consequently we continue to feel alone, abandoned, betrayed, and unloved. But sexual love can be a hidden window onto the spiritual reality. At the height of passion or in the fullness of love, we might suddenly feel transported to a different plane of existence where all of our sensations, experiences, and thoughts occur against the peaceful backdrop of an overriding sense of at-oneness.
Love is so universal in the world that it even underlies the physical forces of nature.
Through erotic passion we overcome our habitual egoistic insularity and reach into the core of other beings. There is a rumor that there were times when sex was practiced in sacred precincts. There, both males and females were in the priestly service of ministering to the worshippers and embracing them within the mysteries of life. I am not sure if this is factual. But the vision and the dream that it ought to have been that way is what makes that thought not just a fantasy.
