According to Osho, being an unripe fruit means you have not fully lived or known your impulses and experiences; you cling to the tree of desire, conditioning, and half-hearted living. Ripeness comes by experiencing totally, seeing the futility of relish, and then renunciation happens by itself; the ego falls. Where man completes himself, the divine begins.
It means you’re still hanging on the branch because you haven’t fully felt things; once you do, you naturally let go.
