Great sex is sheer abandonment, letting go of inhibition and self-consciousness and giving in to the heat of the moment. In Zen, every attachment must go — attachment to ego, self, body, possessions, this world, even to life itself. All this is symbolized in the moment of climax, when two lovers release and experience the feeling of transcendence. Through the Way of Release, we awaken to the God-power within us and glimpse our mortality and immortality at the same time.
— Philip Toshio Sudo, Zen Sex
