Karma yoga expands the heart, breaks all the barriers that stand in the way of realising the ultimate unity and takes you to the door of intuition. It helps you to develop divine virtues such as mercy, tolerance, kindness, cosmic love, patience, self-restraint, etc. It destroys jealousy, hatred, malice and the idea of superiority.
Karma yoga is the yoga of selfless action, without the idea of agency and without expectation of fruits. Work is worship of the Lord. There is indescribable joy in the practice of karma yoga.
A karma yogi should be absolutely free from greed, lust, anger and egoism. Only then can he do real and useful service. A karma yogi should have an amiable, loving nature. He should have perfect adaptability, tolerance, sympathy, cosmic love and mercy. He should be able to adjust himself to the ways and habits of others.
A karma yogi should have an all-embracing and all-inclusive heart. He should have equal-vision. He should have a cool and balanced mind. He should rejoice in the welfare of others. He should have all his senses under control. He should lead a very simple life.
A karma yogi should bear insult, disrespect, dishonour, censure, infamy, disgrace, harsh words, heat and cold and the pains of disease. He should have great power of endurance. He should have absolute faith in himself, in God, in the scriptures and in the words of his guru. Such a man is a good karma yogi and reaches the goal quickly.
The man who serves the world, really serves himself. This is an important point. When you serve a man, when you serve your country, always think that the Lord has given you a rare opportunity to improve. Correct and mould yourself by service. Be grateful to that man who has given you a chance to serve him.
