Acharya Prashant explains that the ego thrives on the superstition of separation, believing itself to be distinct from the rest of existence. He distinguishes between mere motion in nature and "action" in living beings. While a stone moves without a sense of self, a human performs actions with the belief of being the "doer." This sense of doership inevitably leads to being the "enjoyer" or "sufferer" of results, thereby surrendering one's internal state to external circumstances and losing true freedom. We often assume an internal doer exists simply because we see external motion, much like assuming a driver is inside a car with tinted windows without actually looking within.
