According to Osho, up to the fifth body a seeker needs some earthly rasa—a conscious relish of one of the five senses—as a stake that anchors the being to the shore of life; without it, departure is inevitable. Enlightened ones may deliberately keep a simple taste (like food) to postpone leaving and share their treasure. Beyond the fifth body, other forces sustain presence, so bodily rasa is no longer required.
Until you’re very advanced, you need one small, conscious worldly taste to stay here; masters may keep a simple liking, like food, so they don’t leave before finishing their work.
