According to Osho, lifelong celibacy, if forced, does not lead to samadhi; it breeds repression and madness. True celibacy is the natural fragrance of deep, conscious union—perhaps from past lives—where, with relaxed breath and attention at the ajna, a glimpse of samadhi dawns. Having tasted that, one effortlessly transcends sex; without such experience, abstinence remains bondage.
No—celibacy brings samadhi only when it arises naturally after a sacred, conscious experience beyond sex; forcing celibacy won’t work.
