According to Osho, morality (dharma) is not obedience to external rules but effortless living in one’s own nature; sin is any act done by the egoic doer against that nature. When doership dissolves and action flows naturally, stealing or harming cannot occur. Deviation from nature breeds anxiety and suffering; alignment brings peace.
Be true to your deepest, effortless self; forcing yourself against it is sin, flowing with it is virtue.
