Prabhupāda: Here Kṛṣṇa says that "Destruction in the course of performing one's own duty is better than engaging in another's duties, for to follow another's path is dangerous." Now, Arjuna was a military man, a kṣatriya. His business was to fight for the good cause. But in the battlefield he thought that "Why should I engage myself in this killing business? Better retire from it. If I don't get my kingdom, I shall rather beg." This begging business is for us.
Just like we are sannyāsī, or a brāhmaṇa. We are allowed to beg. We are not, of course, begging as professional beggar, but we introduce ourself as beggar. The Vedic culture is that a sannyāsī, when he comes to beg in a householder's house, he receives him very respectfully, and whatever he wants, they want to supply. But they do not want anything, but the introduction is that they take this opportunity of sitting in a householder's home and talk about Kṛṣṇa consciousness. That is their real business. They are not beggars.
Anyway, this begging business is not for a householder or a military man. Therefore Kṛṣṇa say that "Don't try to imitate the business of a sannyāsī or a brāhmaṇa. You are kṣatriya. Your duty is to fight, so you should follow your own prescribed duty. Don't try to imitate others." But one can attain perfection by being engaged in his own occupation, provided he does it in Kṛṣṇa consciousness. So Kṛṣṇa is asking him to fight, and he is a professional fighter. So if he fights in accordance with the order of Kṛṣṇa, there is his perfection. This is the purport. Go on.
Tamāla Kṛṣṇa: Purport: "A living entity, as part and parcel of the Supreme Personality, is originally spiritual and pure, as well as free from all contaminations of matter. Therefore, by nature the living entity is not subjected to the sins of the material world, but factually when the living entity is in contact with the material nature, he acts in many sinful ways without hesitation. As such, Arjuna's question to Kṛṣṇa is very sanguine as to the perverted nature of the living entity. Although the living entity sometimes does not want to act in sin, he is still forced to act. This force is not, however, impelled by the Supersoul living within the living entity, but must be due to other causes, and that is explained in the next verse by the Lord."
Thirty-seven: "The Blessed Lord said: It is lust only, Arjuna, which is born of contact with the material modes of passion and later transformed into wrath, and which is the all-devouring, sinful enemy of this world (BG 3.37)."
Prabhupāda: Yes. Passion, if you increase your passion, then when you cannot fulfill your passion, you'll be angry, wrath, one after another. So this is due to our being situated in the modes of passion.
As I have told you, there are three kinds of modes of material nature. One is goodness, one is passion, and one is ignorance. So ignorance is the lowest quality, passion is still better than ignorance, and goodness is the highest good quality within this material world. And one has to transcend even goodness. Then he can go to the Kṛṣṇa consciousness platform. So one should not remain on the platform of passion. He should try to rise on the platform of goodness, and from there he should try to be promoted in Kṛṣṇa consciousness. This is one method. But if you take to Kṛṣṇa consciousness directly, then automatically you transcend the platform of ignorance, passion, and goodness. Go on.
Tamāla Kṛṣṇa: Thirty-eight: "As fire is converted by smoke... As fire is covered by smoke, as a mirror is covered by dust, or as the embryo is covered by the womb, similarly the living entity is covered by different degrees of this... (BG 3.38)"
Prabhupāda: Lust. Different degrees of lust. Those who are in the modes of goodness, their lust is a different quality. Those who are in passion, their lust is in different quality. Those who are ignorance, their lust is different quality. It is the question...
Just like there are first-class prisoner, second-class prisoner and third-class prisoner. So after all, they are prisoners, maybe first-class, second-class or third-class. That doesn't matter. Similarly, within this material world somebody may be very learned, rich, beautiful, all good qualifications, in the modes of goodness. So they... Or somebody is passion and somebody in lower degree, even animal life. But they are all prisoners within this material world.
One has to transcend this position. One has to transcend even the so-called goodness of the material world. Just like Arjuna was trying to be so-called good man of this material world. He was trying to avoid the injunction of Kṛṣṇa. Kṛṣṇa wanted him that "You should fight this Kurukṣetra battle," but he wanted to be good man. So that fighting, when he was convinced of Kṛṣṇa's instruction, this Bhagavad-gītā, that means he transcended even the goodness platform of this material world. So Kṛṣṇa is trying to raise him to the... traiguṇya-viṣayā vedā nistraiguṇyo bhavārjuna. This whole material atmosphere is surcharged with three modes of material nature. So one has to transcend the modes of material nature. Just like one should not try to become a first-class prisoner. In the prisonhouse, if one is a third-class prisoner and one is first-class prisoner, the third-class prisoner should not aspire that "Let me remain in this prisonhouse and become a first-class prisoner." That is not good. One should transcend the prison walls or come out of the prisonhouse. That is his aim. Go on.
