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.
Why are people so afraid? The answer is that they have made themselves helpless and dependent on others. We are so lazy, we do not want to do anything ourselves. We want a Personal God, a Savior or a Prophet to do everything for us.
-Swami Vivekananda
