According to Osho, you can’t forget by force; the very command “I should forget” keeps the wound alive. Simply acknowledge: it happened. From a wider view, life eventually snatches everything—cheater and cheated end equal when the “game” ends. Seeing this, the grievance loses importance and fades naturally; not suppression, but understanding, dissolves memory’s sting and restores ease.
Don’t try to force forgetting; accept it happened and remember that, in the end, it doesn’t really matter—then the hurt lets go of you.
