What does sex have to do with Tantra?

Because Tantra finds its momentum in surfing the abyss created by duality, what better more challenging - abyss than that of yin and yang? That chasm between action and receptivity? The basic duality of being alive. And what better place to dive in and experience it all than in sexual orgasm? No other human experience demands such a tenuous balance between focused activity and total surrender. And there is such power in it, so much of life and death in it. To enter this moment with total awareness, to taste the orgasm as meditation, is to invite the abyss within . . . to experience the chasm fully. Intimacy with reality brings to the meditator the direct experience of oneness. Not oneness as a concept.
