We are very much busy to make solution of the problems of life. Political problems, economical problems, social problems. They are also problems. But real problem is janma-mṛtyu-jarā-vyādhi, that you have to take birth, you have to die, and when you are in life, you have to suffer from diseases, jarā-vyadhi, and you have to become old. Janma-mṛtyu-jarā-vyādhi-duḥkha. These are really problems. But who knows that these are the real problems? They have taken it, accepted it.
Kṛṣṇa says, "This is knowledge." If you are scientifically advanced how to stop death, how to stop birth, how to stop old age, how to stop disease, then you should know that you have advanced in science. Otherwise what is this? If you have made a horseless carriage motorcar, that is not advancement. It is advancement, but it is not the solution of the problem. The solution of problem is, human life, is to how to stop death.
Therefore śāstra says that nobody should become guru, nobody should become father, nobody should become husband—in this way there is a list—na mocayed yaḥ samupetya mṛtyum, if one cannot help his student or his son or his subordinate to stop death. Actually this is the problem Na mocayed yaḥ samupetya mṛtyum. We are under the clutches of death. "It is as sure as death." So this human life is meant for stopping this death. But if you don't see that this is the problem, that is ajñāna. That is ignorance. If you don't accept this is the problem, if you simply think "My problem is how to eat, how to sleep, how to have sex life, how to defend... These problems are already solved, even by the birds and the beasts. These are not the problems. They are already set up. Real problem is here: janma-mṛtyu-jarā-vyādhi-duḥkha-doṣānudarśanam (BG 13.9).
