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.
When we have become free, we need not go mad and throw up society and rush off to die in the forest or the cave; we shall remain where we were but we shall understand the whole thing. The same phenomena will remain but with a new meaning.
-Swami Vivekananda
