According to Osho, letting go of both negative and positive feelings means seeing their inseparability and dropping all clinging and avoidance. Don’t become numb or neutral—that’s indifference. Live each mood totally, watchfully, and let it pass. In such choiceless awareness, the pendulum of highs and lows loses its grip, and you transcend duality to a quiet center beyond both.
Stop trying to keep only good feelings and push away bad ones; feel both fully and watch them come and go until you rest in a calm, steady you.
