According to karma yoga, the action one has done cannot be destroyed until it has borne its fruit; no power in nature can stop it from yielding its results. If I do an evil action, I must suffer for it; there is no power in this universe to stop it or stay it. Similarly, if I do a good action, there is no power in the universe that can stop its bearing good results. The cause must have its effect; nothing can prevent or restrain this.
-- Swami Vivekananda (1863-1902)
