According to Osho, there’s no lie in pure acting; the lie begins with the sense “I am the doer.” Ego is the supreme falsehood; truth is “God is.” When you act as a wave of the divine ocean, without the claim of doership, action is authentic. Non-doership—acting without ego—is truth; doership breeds all other lies.
The lie is thinking “I’m doing it”; the truth is letting life (God) act through you.
