According to Osho, good and bad in humans don’t need an external yardstick. Like health is known by the absence of disease, goodness is the fragrance when suffering, violence, and inner pathology end. ‘Bad’ announces itself through war, sorrow, meaninglessness, and suicide; ‘good’ is the natural, unforced state of love, joy, and wholeness once those diseases disappear.
You can tell something is bad because it hurts and harms; when that stops, what remains—love and peace—is good.
