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.
The moment you fear, you are nobody. It is fear that is the great cause of misery in the world. It is fear that is the greatest of all superstitions. It is the fear that is the cause of our woes, and it is fearlessness that brings heaven in a moment.
-Swami Vivekananda
