Karma Yoga is consecration of all actions and their fruits unto the Lord.It is selfless service unto humanity without any attachment or egoism.

Action of some kind or the other is unavoidable. You cannot keep quiet without doing anything. What binds you to phenomenal existence or Samsara is not the action but the idea of doership and enjoyership. When action is done without the expectation of fruits, it is liberating. If you act as a participant in the cosmic activity of Nature, without expectation of fruits, that Karma will not bind you.

The practice of Karma Yoga prepares the aspirant for the reception of knowledge of the Self. It makes him a proper Adhikari (aspirant). Ignorant people jump at once to Jnana Yoga, without first having a preliminary training in Karma Yoga. That is the reason why they fail miserably to realize the Truth. They only talk of Brahman. Indulging in all sorts of useless controversies, vain debates and dry, endless discussions. Their philosophy is only on their lips. What is really wanted is practical ceaseless, selfless service.
