Kenneth Rexroth depicts his erotic act outside in nature at night when the moon and stars shine. The depiction is simple, beautiful and suggestive. Nature is not a mere background but the lovers join the great flow of nature and the Cosmos through their sexual act. Lovers are part of nature and the Cosmos. Rexroth says his lover’s body is connected to everything as well as his body, which he calls “a sacramental relationship.” After he becomes one with his lover, his mind reaches nirvana. In this status, his consciousness enlarges and reflects the Cosmos. The binary distinction between nature and spirit and between sexuality and spirit doesn’t exist any more. This kind sexual experience requires a meditative approach. He shows it in his depiction of nature in between sexual acts. To him, nature is a background and content in his individual erotic rite. It is filled with erotic energy. Like prehistoric erotic rites, nature, God, Goddess and lovers become one in erotic actions. Rexroth’s erotic mysticism shows sex can be one of beautiful and holy day-to-day lives to enrich our spirit in modern times when sex can be easily connected to cruelty and violence.
