According to Osho, Tantra sees “sex energy” as the very life-force itself—the dynamic play of polarities (positive/negative, masculine/feminine) pervading all acts of creation, communication, and meditation. Physical reproduction is just one small aspect. True Tantra harmonizes these inner opposites until they unite within, birthing ecstasy, completeness, and non-need, as in Buddha’s inner orgasm; thus every genuine meditative technique is inherently sexual in this wider sense.
Tantra says “sex” really means life energy everywhere, and freedom comes when your inner male and female join in harmony.
