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.
Let us put forth all our energies to acquire that which never fails -- our spiritual perfection. If we have true yearning for realization, we must struggle, and through struggle growth will come. We shall make mistakes, but they may be angels unawares.
-Swami Vivekananda
