What is Karma Yoga? It is Self-Realization in action; liberation through work; freedom by service. It is commonly called the path of action. In whatever state of self-expression we engage, that is action. We think, we love, we work. These are all actions. Karma Yoga is the regulation of all our actions in order that we may realize our innate spiritual perfection. The philosophy of Karma Yoga is the science of work. It teaches us how to perform all our activities that we may find peace and happiness in our daily life. Besides it opens our vision in wisdom whereby we may regain the full consciousness of our ever abiding state of subjective freedom, or salvation.
The beauty of the philosophy and science of yoga is this: That it does not require anything more from its follower than that which he already possesses. Starting on this foundation it helps him to utilize that to regain his absolute freedom.
Karma Yoga propounds this truth. It recognizes that we are constantly working; then why should we not use that activity for the highest purpose of life? Every action can be so directed as to bring us oneness with God.
But there is a secret key to this science of self-emancipation. Karma Yoga gives us that secret key. Therefore, Karma Yoga may be called the secret of work. The same work can enslave us to sense-identification, or reveal our innate freedom. It can drown us in misery, or bring us to the heights of peace. It can make us either restless, nervous, physical wrecks, or calm, dynamic, and strong. It can hide or reveal the Self. It can steep us in ignorance, or free us in wisdom. Karma Yoga tells us the secret of it all. It tell us how to become free from action not through abstention from, but by the performance of action.
