According to Osho, there is no real merging between Indian Tantra and Tao: Tantra is technological, method-based transformation (sex to superconsciousness), while Tao is non-method, pure spontaneity and let-go. Mixing them destroys Tao’s delicacy. Yet Tao embraces sexuality through its own ‘tantra’—not a technique, but spontaneous, natural love and living, learned only by relaxing into life’s flow.
No—Tantra uses methods, Tao is just letting life flow, though Tao welcomes love and sex in a simple, natural, unplanned way.
