Big, big scientists talking all nonsense. No. There is no remedy. They are trying to control birth, so many contraceptive method, even killing their own children, abortion—but still the population increases. Still, every minute, every three minutes or something like, one, like that, I do not know . . . but increasing. Therefore they are perturbed: the population is increasing. So where is your science to stop? That is not possible. So birth, death. Nobody wants to die; the death is there, forced upon you. And birth also, they want to stop. No. Birth is also going on. Birth, death and old age. Who can be free from old age? Everyone wants to remain young man, but that is not possible. Just like I was also a young man. Now I am thinking, "Oh, I am getting old. I am getting old." So where is the process? So birth, death, old age and disease. So long you are in the material body there must be disease. You cannot stop it. You can be very proud that you have manufactured very nice medicine, but why not stop the disease? So that is not possible.
So these are the imperfections of our life—birth, death, old age and disease. And science or advancement of education and so many things—what you call, big, big words, that you may go on—but still you remain imperfect, because you must die. Again, after death, you'll take birth. And as soon as you take birth, your body also becomes older and older, and you must suffer from disease. This is called imperfection. But they have become so dull that they cannot understand. They cannot imagine that one can be perfect against this imperfection. They do not know it.
