According to Osho, the “burning fruit” means the result is the burning itself: the heat of longing, pain, or inquiry is its own completion. When you stay present and taste it totally, nothing remains to be gained or carried—awareness consumes it. Having fully burned, the hand is free; the suffering ends and leaves no residue to cling to.
The painful fire was the whole point—once you feel it completely, it finishes and lets go of you.
