Tathā dehāntara-prāptiḥ. Dehino 'smin yathā dehe (BG 2.13). This is the first understanding of knowledge, but people do not understand that within the body there is soul. They are so fool. Therefore they have been described in the śāstra, sa eva go-kharaḥ: (SB 10.84.13) "This class of men, they are no better than the cows and the asses." So you cannot become happy in the assembly of some animals. Therefore people are so much disturbed at the present moment. There is no sober life, dhīra. If you want peaceful life in the society, then you must accept this program. Cātur-varṇyaṁ mayā sṛṣṭam (BG 4.13). There must be brahminical class of men, kṣatriya class of men, vaiśya class of men.
The vaiśya... Generally, we understand, vaiśya means the mercantile class of men. No. At the present moment the so-called vaiśyas are śūdras, less than śūdras. Why? Now the vaiśya's business is kṛṣi-go-rakṣya-vāṇijyaṁ vaiśya-karma svabhāva-jam (BG 18.44). The vaiśyas must be engaged in producing foodgrains, but they are not interested. They are interested for opening factories for bolts and nuts and tires, Goodwheel tires, Goodyear tires. Now you eat tire and bolt nut. No, you cannot eat. You have to eat rice, and rice is ten rupees per kilo. That's all. Because no vaiśya is producing food grains. This is the defect.
They don't see the defect. They're simply howling, bawling, "Oh, it has increased price". Why not, increased, price? There are millions of people in Bombay city. Who is producing food grain? But they are known as vaiśya. What kind of vaiśya? There is no brahminical culture; there is no brain. There is no kṣatriya who can give you protection. There are so many defects.
So if you want to remodel your life, the society, the human society, nationally or internationally—everything is spoken here, international—then you have to take to the advice of Kṛṣṇa. This is the purpose of Kṛṣṇa consciousness movement: wholesale, thorough, overhauling of the human society. We have not manufactured anything, concocted things. It is very scientific. If you actually want to fulfill the mission of your life, then you have to take to this advice of Bhagavad-gītā, very scientific and spoken by the Supreme Personality of Godhead, without any defects.
If I speak something, there may be so many defects, because I am imperfect. Every one of us, imperfect. We commit mistake. To err is human. There is no human being who can say boldly that "I never committed any mistake." That is not possible. You must commit mistake. And sometimes we are illusioned, pramāda. That we are all, because we are accepting this body as "I am," which I am not. That is called pramāda, bhrama pramāda. Then vipralipsā. I have got bhrama, I commit mistake, I am bewildered, I am illusioned. Still, I am taking the position of teacher. That is cheating. If you are defective, if you have got so many defects in your life, how you can become teacher? You are a cheater. Nobody's teacher, because without being perfect, how you can become teacher? So this is going on.
