A sinful man cannot earn money honestly. Just like a thief: because he has adopted the means of earning money by sinful activities, he cannot take to honest work. He can work, but he is accustomed to steal. He knows that "This work is not good." If he is arrested, he will be punished. He has seen that one thief arrested and punished, and he has heard also that if one steals, he will be punished. And he has heard also from the śāstra, either law book or Vedic literature, that "Stealing is not good. It is punishable." But still, he does it. That means a sinful man cannot restrain himself from sinful activity. He has to do it. Kāraṇaṁ guṇa-saṅgo asya sad-asad-janma-yoniṣu (BG 13.22). Unless you give up the particular association with the modes of nature, it is not possible for him to restrain himself from committing sinful activities.
So he became sinful because he left his married wife and he became attracted with a śūdrāṇī immediately. That has been described in the previous verse, visasarjācirāt pāpaḥ (SB 6.1.65). Pāpaḥ means sinful man. He became sinful immediately. Therefore we stress on marriage. They cannot understand why this Association stresses so much for marriage, not to live. . . They live as friend; that is śūdra. There is no legal marriage, śūdra and śūdrāṇī. Just like he was living with the śūdrāṇī—he was not married—as friend. So even śūdra's marriage there is. For the śūdra there is one āśrama—that is gṛhastha āśrama. And for the brāhmaṇas, four āśramas: brahmacārī, gṛhastha, vānaprastha, sannyāsa. This is for the brāhmaṇas. For the kṣatriyas: brahmacārī, gṛhastha, vānaprastha. For the vaiśya: brahmacārī and gṛhastha. And for the śūdras: no brahmacārī, only family life, and that also sometimes without marriage. This is the low grade, first grade, second grade.
So now to live as friend, as śūdra, that is now current all over the world. Now marriage is being forgotten. That is also written the śāstra, that "There will be no more marriage. One man and woman should live together by agreement." That is going on now in Kali-yuga. Svikāram eva hy udvāhe, it is stated. Simply agree: "Yes, you become my bedfellow; I become your bedfellow." That's all. Svikāram eva hy udvāhe. That is marriage. No more that ceremonial marriage. That is being forgotten. This is Kali-yuga now. Dāmpatyam eva hi. . . Ratim eva hi dāmpatye: "And their so-called unity, man and woman, means sex." There is no other meaning. Dāmpatye, union of man and woman, means sex. There is no other religious system, I mean, that husband, wife live together; they should cooperate for advancing in Kṛṣṇa consciousness. These things are being forgotten.
