If there is no Atta or the permanent soul, how could Kamma [Karma], good or bad actions, give its result to the doer?
Buddhism denies Atta or the permanent soul to be attached to, but admits the continuity of life from one to another, as long as one does not reach Nibbana or the utter extinction of the fire of defilements and he fire of suffering. Whenever human or animal beings continue to transmigrate in the cycle of life from birth to death and from death to rebirth, kamma still continues to give its result to the doer.
