Everyone is engaged in action, The Law of Karma means that there are reactions to every action and people must endure the reactions to their actions. The second mantra of the yogic scriptres Shri Isopanishad refers to Karma Yoga or devotional service. "A person may desire to live for hundred years if he works according to this truth because that sort of work will not bind him to the law of karma. And there is no alternative for man.
