A conditioned soul tries to enjoy material happiness again and again. Thus he chews the chewed. But sometimes, in the course of such enjoyment, he becomes relieved from material entanglement by association with a great soul. In other words, a conditioned soul is always engaged in some type of sense gratification, but when he understands by good association that it is only a repetition of the same thing, and he is awakened to his real Krishna consciousness, he is sometimes relieved from such repetitive so-called happiness.
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.
