A Krishna conscious person is always dovetailed with the supreme desire, for he has no desire for personal sense gratification. He moves exactly like a part of a machine. As a machine part requires oiling and cleaning for maintenance, so a Krishna conscious man maintains himself by his work just to remain fit for action in the transcendental loving service of the Lord. He is therefore immune to all the reactions of his endeavors. Like an animal, he has no proprietorship even over his own body.
A cruel proprietor of an animal sometimes kills the animal in his possession, yet the animal does not protest. Nor does it have any real independence. A Krishna conscious person, fully engaged in self-realization, has very little time to falsely possess any material object. For maintaining body and soul, he does not require unfair means of accumulating money. He does not, therefore, become contaminated by such material sins. He is free from all reactions to his actions.
