it is the duty of everyone to use the senses for Kṛṣṇa. Just like the property of somebody should be used for him, not for others. I have given this example many times. Perhaps you may remember. Suppose here is the assembly, and there is one hundred dollar note is there, fallen from somebody's pocket. So if I take or you take the hundred dollar note and put your in the pocket, "Here is a hundred dollar note," then you are a thief, because that hundred dollar note does not belong to you. You are taking it without his information. That means you are a thief. This is called bhoga, enjoyment. And another is tyāga. One thinks, "Oh, why shall I touch it? Somebody's . . . let it remain there. I have no . . . nothing to do." This is called tyāga, giving up.
So the hundred dollar note is the same. One is trying to enjoy it, and one is trying to give it up: "I don't care for it." So both of them are fools, bhogī and tyāgī. Bhogī means the karmīs. The karmīs, those who are working very hard, utilizing . . . the scientists are utilizing the resources, material resources. That means all are making policy how to steal that note. That is their policy, the karmīs. And another, while he was unable to steal, he says: "Oh, grapes are sour. There is no need of . . ." That is tyāgī.
So both the bhogīs and tyāgīs, two classes of men, you'll find. Mostly they're bhogīs. They're trying to enjoy anything for his sense gratification utility. And another, when he's baffled, he says, "No, no, we don't require it." Similarly, the same example: If one takes that note and says: "Somebody has lost his hundred dollar note, sir," so one who has really hundred doll . . . he says: "Yes, yes. I had . . ." And if you deliver to him, that is real service.
To give up that note or to take that note, both is useless. So similarly karmī and tyāgī, bhogī and tyāgī, they're all useless. And bhakta, devotees, they know that everything belongs to Kṛṣṇa; now it should be offered to Kṛṣṇa. That is real service. The same example: You take the hundred note and you ask, "To whom this hundred dollar note belongs?" If you give him, that's a great service. That man becomes very much pleased upon you: "Oh, you are so nice."
So similarly, this everything belongs to Kṛṣṇa. What is this body? This body, material elements: earth, water, fire, air; and then within the body, subtle psychological: mind, intelligence, ego. So Kṛṣṇa claims, "All these eight elements are My separated energy." Then where is your body, your mind? You cannot . . . you do not know even how this body is working. Although I am claiming, "This is my body . . ." Take, for example, just you are a tenant in an apartment. You are getting all supplies. But you do not know that how these, I mean to say, tap water is working, fire is working. You do not know. But you pay rent, or somehow or other, you have occupied the apartment—you are utilizing. Similarly, we are utilizing this body. But this body does not belong to me, it belongs to Kṛṣṇa. This is real fact.
