What is karma and how does it work

The Buddha taught that because of karma, beings are bound to the ever-turning wheel of rebirth. Only when a person stops believing in the existence of a permanent and real self can he or she become free from karma. Bhikkhu Bodhi, Jan Chozen Bays, and Jeffrey Hopkins discuss what that means.
