In the Bhagavad-gītā it is plainly said, mūḍha. Mūḍha means asses, rascal. He does not know his own interest. He is called mūḍha, ass. Just like ass. Ass is whole day working with tons of cloth on his back, but he does not... Not a piece of cloth belongs to him. This is ass. And he is working so hard only for a morsel of grass, which is available everywhere. But he is thinking that "This gentleman, washerman, is giving me food." This is ass. Such food can be available anywhere and everywhere, but he is thinking like that and working so hard. So karmīs are like that. He will eat two capātis or four capātis, but he is working day and night. If you want to see him, he will say, "Oh, I have no time." He does not think at any time that "I am interested to eat four capātis, which can be very easily available. So why I am working so hard?" But that sense does not come. He is working, working, working, "More money, more money, more money, more money, more money." The Bhāgavata says, "No, no. This is not your business." The four capātis is already destined to you; you will get, any circumstances. You don't waste your time simply under some false impression of economic development. Don't waste your time. You cannot get more, you cannot get less. That is already there. So you utilize your time for understanding Kṛṣṇa. That is your business. People will not accept it. "Oh, this is a waste of time. Attending the class of Bhagavad-gītā, this is waste of time. By this time I could have earned hundreds of dollars." That is their business. That is called durbuddhi, durbuddhi, not very intelligent. All mūḍha, asses.
Real intelligent person is he who is satisfied what Kṛṣṇa has given him: "If Kṛṣṇa wants, He will give me more. Let me become Kṛṣṇa conscious. Let me study about Kṛṣṇa. Let me chant about Kṛṣṇa. Let me hear about Kṛṣṇa. Let me see with my eyes Kṛṣṇa, the Deity Kṛṣṇa. Let me engage my hands in worshiping Kṛṣṇa, in cleansing the temple, my hands. Let my legs be engaged in going to the temple." In this way all our senses should be engaged in the service of Kṛṣṇa. That is our real business.
