The vaiśyas, food production means produce food grains, agricultural. By agriculture, you can . . . So much land is vacant all over the world. They are producing coffee. I have seen in Africa, vast land is engaged in producing coffee. No food grain. So this is the defect of the civilization. They do not know how to live. Will man die without drinking coffee? No. That is not the fact. But man will die if they have no real food, anna, food grains. If you think that "I eat meat. I don't require food grains," but the cows, the animal eat food grains. So without food grain, how we can live? Therefore Kṛṣṇa says in the Bhagavad-gītā, annād bhavanti bhūtāni (BG 3.14). You produce food grains. Why you are producing so much unnecessary things—television and tools, and stool also, so many thing? Why? They are not necessary. Live in the village, produce your own food, your own cloth, and drink milk sufficiently—all economic questions solved. Then you become suśīla, well behaved. And if you go on killing animals and drinking wine and gambling, when you will be suśīla? You are always bad character.
Here it is said suśīla, "well behaved," "good character." Suśīlāḥ sādhavaḥ. Sādhavaḥ, character like ideal. You have got ideal, Lord Jesus Christ. Suśīlāḥ sādhavaḥ nārāyaṇa . . . Why? Nārāyaṇa-parāyaṇāḥ: because they are devotee of Nārāyaṇa. If you become simply nārāyaṇa-parāyaṇa, devotee of Nārāyaṇa or Kṛṣṇa, all good qualities will come to you automatically. All good qualities. Yasyāsti bhaktir bhagavaty akiñcanā sarvair guṇais tatra samāsate surāḥ (SB 5.18.12). Take practical example. These boys, these girls, how they have become so nice? They are known as "bright-faced." Why? Because nārāyaṇa-parāyaṇāḥ: they have taken seriously Kṛṣṇa as the object of worship. So actually if you want happiness within this world, peace and prosperity, just become Kṛṣṇa conscious. All problems will be solved, and you will be happy.
