First of all technology of the senses, and then, next higher technology is of the mind, which is known as psychology. Thinking, feeling, willing. They are trying to understand how they are working. And above this mind, mental science, there is the science of intelligence. And above the science of intelligence, the background is the soul. Unfortunately, we have got technology for the bodily senses, we have got technology for psychology, but we have neither any technology for intelligence nor for any technology in the science of the soul. The Krishna consciousness movement is the technology of the science of soul.
There is a nice story. You'll appreciate it. In India, especially in Bengal, there are many rivers. The land is full of rivers. Because it is on the bank of the Bay of Bengal, all rivers are falling. Especially the East Bengal, is full of rivers. One student of technology was going home, and he was on the boat. So the student was asking the boatman, "Do you know what are the stars?" The boatman said, "Sir, we are ordinary boatman. What do we know about these stars?" "Oh. Then your fifty percent of life is wasted, useless." Then he was asking, "Do you know what are these trees? Do you know any science of botany?" He said, "Sir, we are ordinary laborer. What do we know about botany?" "Oh. Then seventy-five percent of your life is useless." In this way the student of technology was asking the boatman, "Do you know this? Do you know that?" And he said that, "I am ordinary man. What do I know all these things?" Then all of a sudden there was a black cloud, and there was storm, and the river began to be inflated, and the boatman said, "My dear sir, do you know swimming?" "Oh," he said, "no." Then he said, "Then your cent per cent knowledge is spoiled. Now you have to go down to the river. Your life is finished." In this way they dropped in the river, and the technological student, because he did not know how to swim, so the storm and the waves grabbed him.
The idea is that we are making progress, certainly, in technology, in economics, in so many other departments of human necessities. But Bhagavad-gita says that real problem of this world, or real problem of our life, it is said in the Bhagavad-gita, janma-mrityu-jara-vyadhi-duhkha-doshanudarsanam [Bg 13.9]. If you are intelligent enough, then you should see the real problem is birth, death, old age and disease. Janma means birth, and mrityu means death. Janma-mrityu-jara. Jara means old age, and vyadhi means disease. So actual material problem is this, janma-mrityu-jara-vyadhi. We have forgotten that, "In the abdomen of my mother, how precarious condition I was living in." Of course, we can know from the description of medical science or any other science how the child is packed up there and how much suffering is there. The worms bite the child and he cannot express; he suffers the suffering. Similarly, the mother eats something, and the pungent taste also gives him suffering. So these descriptions are there in the sastras, in the scriptures and authentic Vedic literature, how the child suffers within the abdomen of his mother.
So these are the sufferings of birth. At least, one child has to remain in that air-packed condition at least for ten months. Now just imagine if you are put into that air-packed condition for three minutes now, you will immediately die. But actually, we had that experience to remain in the mother's womb in that air-packed condition for ten months. So suffering was there, but because the child was incapable of expressing, or his consciousness was not so elevated, he could not cry, but the suffering was there. Similarly, at the time of death there is suffering. Old man, just like us, we have got so many complaints, bodily complaints. Because now everything, the anatomical or physiological condition, is deteriorating. The stomach is not digesting foodstuff so nicely as when I was young I could digest. So the sufferings are there. Similarly, disease. Who wants disease? So modern technology, they have advanced undoubtedly, but there is no remedy for, I mean to say, to stop birth, death, old age and disease. This is real problem. But because these problems cannot be solved by the modern scientific advancement of knowledge, they have practically set aside or neglected because they cannot solve it.
