If we do not live regulated life, if we do not follow the regulative principles as they are given in the śāstra, then in spite of being put into jail, in spite of my suffering, as soon as I come back, I again commit the same thing and again go to jail. This is... The example is given very nicely here that if anyone does not know how to live hygienically, healthfully, he must fall diseased. That's a fact. Similarly, one must have knowledge what is the value of this life, how I shall live, then he will be not subjected to the sinful activities. This is the conclusion. And if he lives like ass and cow, without any knowledge, without knowing the values of human life, then he must be subjected to sinful activities and will be punished one after another, accepting different types of bodies.
The different types of bodies means that is our punishment. We may think it as happiness, but as soon as you accept a material body, you are subjected to the four principles of material distresses. What is that? Janma, mṛtyu, jarā, vyādhi. You may think that you are very scientifically advanced—"There is no more distress in my life"—but Kṛṣṇa says, "No. If you are intelligent, then you should think of these four principles as distresses." What is that? Birth, death, old age and disease. But the modern so-called scientists, they cannot make any solution to birth, death, old age and disease; therefore they have left them aside: "Oh, don't care for them." That is ignorance. Our real problem is not this temporary problem that we are in such and such distressed condition. That is temporary.
