Action is the most natural thing in a being no one can live without performing action. Action is of three types, mental, verbal, and physical.   In Karma Yoga one is required dedicate all his actions to God.   The doer-ship of action and the results of the fruits of action have to be surrendered to the Lord.     Selfless service has to be performed to the entire humanity and nature.   One has to work for the Lord’s sake not for ones own self.   These selfless actions result in purification of the mind and resultant God-realization.

Yoga of action also implies that one has to perform ones bounden duty. No one is permitted to escape the duty as per ones birth place and circumstances. If one is a military man, he cannot escape his duty by not going to a fight or by adopting an attitude of following the principles of non-violence. A doctor cannot put his patient to death by saying that he was suffering from an incurable disease, the bounden duty of the doctor is to cure the patient not kill the patient, how so ever bad the suffering of the patient maybe.    A judge has to pronounce the right judgment in accordance with the law; he cannot deviate due a prevailing pressure or political circumstance.  Non -performance of   

Bounden- duty is a very serious offence and hinders all spiritual progress.
