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.
Learning and wisdom are superfluities, the surface glitter merely, but it is the heart that is the seat of all power. It is not in the brain but in the heart that the Atman, possessed of knowledge, power, and activity, has its seat.
-Swami Vivekananda
