Those who are using their merit for Kṛṣṇa consciousness, they are sukṛtina. And those who are using their merit for nothing, uselessly, for sense gratification, they are called duṣkṛtina. Both of them are using merit. It is not that a sinful man, a rogue, a thief, a dacoit, has no merit. He has got good merit, but he's utilizing for different purpose. Therefore they are called duṣkṛtina. Merit should have been . . . just like we have got human merit, better than the animal merit.
So this merit is being misused to improve the process of eating, sleeping, mating and defending. If you improve this process of this eating, sleeping, that does not make you very advanced in civilization. The animal is also eating. Whatever, according to the nature, they are destined to eat, they are eating. Similarly, we are also eating, but we are not eating according to the, I mean to say, indication of nature.
Take, for example, our teeth and animal teeth. There is difference. Our teeth . . . this is scientific. Our teeth is meant for eating vegetables and fruits. It is so made. If you eat continually vegetables and fruits, you'll not be attacked with pyorrhea. But if you eat meat—your teeth is not meant for eating meat—you'll very soon be attacked with pyorrhea because breaking the laws of nature. This is one example.
Similarly, in our eating, sleeping, mating and defending we are using so many wrong things. Just like formerly there was also fight. That fight was being conducted with arrows and bows. So if you want to kill your enemy, you'll kill your enemy, not others. Other innocent people will not be killed. But nowadays, for defending, we are using atom bomb. So many thousands of innocent men are being killed.
So therefore to manufacture or to invent such weapons, lethal weapons, is requiring very good merit—but duṣkṛtina, for committing sinful activities. Even war, there is dharma. That can be also dharmāviruddha. Just like Arjuna fought. He fought dharmāviruddha, under the guidance of Kṛṣṇa. That is not ordinary fighting. That fighting is Kṛṣṇa, because he was fighting under the guidance of Kṛṣṇa. Personally he refused to fight, but when he understood that Kṛṣṇa wanted that fighting, under His guidance he fought. That fighting is Kṛṣṇa.
So similarly, there are actions, different actions. Some of them are duṣkārya and some of them are sukārya. Sukārya means when you act such action under the guidance of Kṛṣṇa, that is nice. And when you act under your whims, then that is miscreant. So miscreants, and they act like human beings, mūḍha and narādhama. Narādhama means . . . nara means human beings, and adhama means the lowest. Just like we accept some caṇḍāla as narādhama. Or . . . there are many low-grade people, but actually, a caṇḍāla is not a low-grade people, man. The man who does not take to Kṛṣṇa consciousness, he is supposed to be narādhama, because he has got the chance.
An animal hasn't got the chance to become Kṛṣṇa conscious. I cannot call animals, cats and dogs, in this meeting. That is impossible, because they have no chance. But we can call . . . we can hold a meeting amongst the human beings for discussing Kṛṣṇa because they have got the special power to understand. This special power to understand Kṛṣṇa, if it is misused for other purposes, he is narādhama. He got the chance of human being, but he has become degraded on account of his unwillingness to take Kṛṣṇa consciousness.
So such persons, duṣkṛtina, always engaged in mischievous activities, always engaged to work hard like an ass and does not take the advantage of human being, they are called duṣkṛtina, mūḍha, narādhama. Then one may say, "All right, these people are lowest of the mankind or like an ass or miscreant, but there are many, many educated persons, highly elevated in discussing philosophy. Why they do not take to Kṛṣṇa consciousness? Why they say that, "God is nirākāra," "There is no God," "I am God," "You are God"? Why do they say? Why do they not take to Kṛṣṇa consciousness?
This question may be raised also. "They are not fools. They are very highly learned. They have undergone tapasya, sannyāsī. Why do they not take shelter of Kṛṣṇa?" Kṛṣṇa is answering to that question, māyayāpahṛta-jñānāḥ (BG 7.15). Yes, they are advanced in knowledge undoubtedly, but because they are āsuri bhāvam āśritāḥ . . .
Āsuri bhāvam means atheistic principle, "There is no God. I am God." This is called atheistic or āsura. Just like Rāvaṇa. He was very much materially advanced. He was very good scholar in Vedic literature. He was son of a brāhmiṇ also, very powerful. But he did not believe in Rāma, God. That was his only fault. Therefore he is described as asura, rākṣasa. Similarly, Kaṁsa, Hiraṇyakaśipu.
So anyone, however materially he may be advanced in education or knowledge, may be Ph.D. or D.H.C. or something like that, if he does not believe in God, he is to be supposed that māyā has taken away his real knowledge. In spite of his education, he is fool number one. Māyayāpahṛta-jñānāḥ.
Why such things take place, that a learned man becomes foolish without understanding Kṛṣṇa? Because āsuri bhāvam, because he has accepted the atheistic principle, "There is no Kṛṣṇa. There is no God." Only for this reason, in spite of educational qualification, he cannot understand Kṛṣṇa. And because he cannot understand Kṛṣṇa, therefore he cannot take to devotional service. These are the description. Na māṁ duṣkṛtino mūḍhāḥ prapadyante narādhamāḥ (BG 7.15).
But there are certain jñānīs who are actually sincere to know the Absolute Truth. Such persons, even they may be misled in one life, two lives, three lives, but at the end they come to the conclusion that Kṛṣṇa is everything. Vāsudevaḥ sarvam iti. Bahūnāṁ janmanām ante jñānavān (BG 7.19).
Here it is said that māyayāpahṛta-jñānāḥ. So long there is influence of māyā, he is lost of real knowledge. But in spite of that, if he makes progress in understanding the Absolute Truth, then, after many births, not in one birth—bahūnāṁ janmanām ante—when he comes to the actual point of knowledge that Kṛṣṇa is everything, vāsudevaḥ sarvam iti, prapadyante (BG 7.19), he surrenders.
That means to surrender unto Kṛṣṇa is the ultimate goal of all knowledge, all activities, all tapasya, all yoga. If one does not reach that point, then he is simply wasting his time and energy.
