If you become Kṛṣṇa conscious, then you can get a body . . . not get, you have already got the body, spiritual body. And upon that spiritual body, this material body has developed. Just like dress. Your coat is cut according to your body. Similarly, this materially body is cut 19:25 according to our spiritual body. So we have got our spiritual body. This material body is covering. Vāsāṁsi jirṇāni. Just like dress. Your shirt and coat is the covering of your real body. Similarly, this body, gross body and subtle body, made of material elements . . . The gross body is made of earth, water, air, fire, and the subtle body's made of mind, intelligence and ego. This is the shirt and coat. Within this shirt and coat, there is the soul.
So the soul is now encaged in this material body. And our business in the human form of body . . . in animal form of body, we cannot do this. But the human form of body we can understand that "I am not this body." The is, the body is, this material body, is a outer encagement, and, because I have got this body, I am subjected to birth, death, old age and disease. Now, in the human form of body . . . I understand it. So if I take the process, how to get out of this cycle of birth and death, then our human life is successful.
This is Kṛṣṇa consciousness movement. How . . . we are helping people how to get out of this material body and revive your own spiritual body and, in that spiritual body, you go back to home, back to Godhead. This is the process. Tyaktvā dehaṁ punar janma naiti (BG 4.9). But people are so attracted to this material body that they are prepared to become cats and dogs next life, but they are not prepared to go back to home, back to Godhead. This is the problem.
So why this problem? Because the human society is in chaos, a chaotic condition. There must be division of four classes. One class must be brāhmaṇa, intelligent class of men. And one should be kṣatriya, one class, the administrator. Because human society, they require good consulting brain, good administrators, good producers and good worker. That is the division of brāhmaṇa, kṣatriya, vaiśya, śūdra. Therefore Kṛṣṇa says, catur varṇyaṁ mayā sṛṣṭam (BG 4.13). In order to keep smooth facilities for human life, there must be four divisions. If you say that don't . . . "We don't require brāhmaṇa,". . . if you don't require brāhmaṇa, then you'll suffer.
Just like you have got this body. And if you think, "This part of the body's very expensive, always eating. Cut it off," then you will dead. Similarly, just to keep your body in good condition, in living condition, you must have your head, you must have your arms, you must have your belly, you must have your legs. You cannot say that "I can avoid this part of the body." No. Similarly, catur varṇyaṁ mayā sṛṣṭam (BG 4.13), the four divisions of the society must be there. Otherwise it will be chaotic, or dead body.
