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 wind of divine grace is always blowing. You just need to spread your sail. Whenever you do anything, do it with your whole heart concentrated on it. Think day and night, I am of the essence of that Supreme Being-Consciousness-Bliss. What fear and anxiety have I?
-Swami Vivekananda
