To understand Kṛṣṇa is very difficult job. Kṛṣṇa has personally said in the Bhagavad-gītā:
- manuṣyāṇāṁ sahasreṣu
- kaścid yatati siddhaye
- (BG 7.3)
"Out of many, many millions of persons," not only in this age, in the past also . . . manuṣyāṇāṁ sahasreṣu, "Out of many millions of persons,"kaścid yatati siddhaye, "one is trying to become perfect." Generally, they have no knowledge what is perfection. Perfection they do not know. Perfection means to stop this process of birth, death, old age and disease. That is called perfection. Everyone is trying to be perfect, but they do not know what is perfection. Perfection means this: that when you are free from these four imperfections. What is that? Birth, death, old age and disease. Everyone. Nobody wants to die, but there is forcefully: you must die. That is imperfection. But these rascals, they do not know. They think that we must die. But no. Because you are eternal, you are not meant for death, but nature is forcing you, "Must die." "Sir, I have got many business to perform." "No, immediately die." Where is your science to stop it?
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.
