As we are forming our consciousness, so we are changing our body. If we make our consciousness doggish or hellish, then we get the body of a dog or an animal or something like that. And if we make our consciousness godly, then we make our next life as good as God. This is the process.
So we have to . . . this is the opportunity. The highest intellectual form of human body when every . . . I mean to say senses perception, sense perception, consciousness, everything is perfect, we have to utilize that for becoming Kṛṣṇa conscious, so that our this process of birth and death can be stopped and we get our eternal body. If we practice this Kṛṣṇa consciousness, then our next life is as good as Kṛṣṇa, which means that there is no more birth, there is no more death, there is no more disease and no more old age.
In the Bhagavad-gītā it is said that one who is intelligent, he will see four things before him. You may be very great scientist. You may be very much advanced in material science. You may be able to construct
(break) skyscrapers, and many millions of motorcar, but you have to think whether you have solved the real problem (break). The real problem of life is birth, death, disease and old age. Not that to live in a high skyscraper our problems of life is solved. No. The problem of life is how to stop these four things: birth, death, old age and disease.
But we have neglected the real problems of life. And we are misusing our intelligence for constructing big buildings and constructing or increasing the so-called bodily necessities of life. The bodily necessities of life are four only. What is that? Eating, sleeping, mating and defending. To maintain this body you require to eat something. Everyone is eating. You are eating, the cats are eating, the dogs are eating, the birds are eating. They have no economic problem. Eating is there already. Have you seen ever that a bird is dying for want of eating, eatables? No. So these things are already arranged. That is no problem. In every form of life your eatables are there by nature's supply.
