The law of karma is inevitable. But there are many ways by which we can escape from the chain of the law of causation and Karma Yoga is one of those ways.
Nature, body, mind go to death, not we. We neither go nor come. The man Vivekananda is in nature, is born and dies; but the Self we see as Vivekananda is never born and never dies. It is the eternal and unchangeable Reality.
-Swami Vivekananda
