Acharya Prashant explains that the law of karma is widely misunderstood as a system of rewards, punishments, or a cosmic balance sheet of debits and credits. He clarifies that the law of karma is actually the law of the doer, or the actor. The fundamental principle is that the actor and the action are inseparable. It is futile to attempt to correct one's actions while the actor remains flawed and determined to stay that way. Therefore, one should shift focus from the action itself to the internal state of the doer.
