Kṛṣṇa says mūḍha. Na māṁ duṣkṛtino mūḍhaḥ prapadyante narādhamaḥ (BG 7.15). Those who are not Kṛṣṇa conscious, not surrendering to Kṛṣṇa, their categories have been explained that sinful, duṣkṛtina. Duṣkṛtina means duṣkārya. And kṛti, kṛti means very meritorious. But duṣkṛti: merit is being misused for some nonsense activities. Therefore duṣkṛti. There are two kinds of activities: sukṛti and duṣkṛti. Sukṛti means for some good purpose, and duṣkṛti, for some bad purpose. That is called . . . so we are all engaged, always engaged to engage our brain to manufacture something will be very facilitous for committing sinful activities. That is science, advancement of science. So many things. Just like contraceptive now advertised by the scientist, "Now, here is a very nice contraceptive. Use it." That means people will take of the scientific advancement and entangle him in sinful activities. That's all. Duṣkṛtina: meritorious, but it is used for sinful activities. That is called duṣkṛtina.
So this class of men—those who have got merit, but it is not being used for useful purposes; for some sinful activities—they are called duṣkṛtina. This class of men, atheist class of men, they will never surrender to Kṛṣṇa. Na māṁ duṣkṛtino mūḍhāḥ prapadyante narā . . . mūḍha, and they do not understand that he has to face so much trouble in birth and death and old age, and he has no knowledge how to stop it. Therefore they are mūḍha, rascal. Na māṁ duṣkṛtino mūḍhāḥ prapadyante narādhamāḥ. And lowest of the . . . human mind, human brain, can understand that "I am suffering," but because he is not understanding, therefore he is the lowest of the humankind, narādhamāḥ. These things are described in the Bhagavad-gītā. "No, they have passed M.A. degree, or Ph.D., M.A." No. Māyayāpahṛta-jñānāḥ. The knowledge has no value because it is māyā. He is thinking . . . he is employing for temporary happiness, māyā, māyā happiness. Māyā-sukhāya bharam udvahato vimūḍhān (SB 7.9.43). He has learned engineering, and planning very high skyscraper building, but he does not know how long he will live that skyscraper building. Say, twenty-five years, fifty years, that's all. Māyā-sukhāya, temporary happiness. He is engaging his brain in so stupendous, horrible work, ugra-karma. Māyā-sukhāya bharam udvahato vimūḍhān. Real business he has neglected, how to get out of these clutches of birth and death, and he's engages his brain for manufacturing a skyscraper building, and he is thinking, "Now advancement of knowledge, advancement of education." This is going on.
Therefore, if we want to save ourself from the fierceful condition of this material life, then we must take shelter of the Supreme Personality of Godhead. That is the verdict of the all śāstras, and Kṛṣṇa comes for this purpose, and Kṛṣṇa's devotees work day and night for this purpose, and that is called Kṛṣṇa consciousness movement.
Thank you very much.
