According to Osho, individuality is your inborn essence (swabhava), unique and rebellious; personality is a socially borrowed mask (persona), the learned façade centered in ego. Society trades your individuality for conformity. When ego—the center of personality—drops, personality dissolves and only your authentic essence remains: the atma, God-centered being, your original face. Then actions flow spontaneously from truth, not social convenience.
Your real self is like your naked body; the “personality” is clothing others put on you—when you drop the clothes (ego), only your true self, the soul centered in God, remains.
