According to Osho, calling violence a disease in psychic anatomy means the mind has fractured into competing parts; no unified, aware center governs, so shifting fragments seize control—now anger, then repentance—without communication. Violence is this disintegration. Nonviolence is mental health: reintegration of the many minds under the awakened inner master, restoring wholeness and coherence.
Violence happens when your inside is split into many bosses fighting; healing is when the real boss—awareness—returns and unites them.
