According to Osho, neither yoga-as-knowledge nor devotion is strictly required together for inner withdrawal; either path can reach the divine. Yet he warns against spiritual miserliness: choosing only the bare minimum makes the journey dry and transactional. He invites overflow—let head and heart meet—so pratyahara becomes not just restraint but a flowering, where clarity and love together unveil a more ecstatic, poetic face of the divine.
You don’t have to use both yoga and devotion to turn inward, but blending them makes the experience deeper and more joyful.
