Kṛṣṇa said. Why one has become nicely situated? Why one is situated, one man is . . . one living entity is eating very nicely very nice foodstuff, and another animal is eating stool? This is not accidental. This is not accidental. Karmaṇā daiva-netreṇa (SB 3.31.1). Because one has acted in such a way that he has to eat stool, he must eat. But the māyā, the illusory energy, is so clever that while the animal is eating stool, he's thinking, "I am enjoying heaven." This is called māyā. So even by eating stool he's thinking that he is enjoying heavenly pleasure. Unless he's covered by that ignorance, he . . . if he remembers that "I was . . . in my previous life I was human being, and I was eating so nice foodstuff. Now I am obliged to eat stool," then he cannot prolong. That is called prakṣepātmika-śakti-māyā. We forget. Forgetfulness.
So this forgetfulness is going on. Evaṁ sva-karma-patitaṁ bhava-vaitaraṇyām anyonya-janma maraṇa. Here is again, anyonya-janma: "Not only this birth, but another birth, another birth, another birth." You cannot say that "This is the final" or "This is the beginning." No. That is not. Anyonya-janma-maraṇa. In another body also there is birth and death. As in this body we have got birth and death, similarly, in another body also, either I take my birth as Lord Brahmā or a small, insignificant ant, it doesn't matter. Any material body you take, there is birth and there is death. You may live . . . just like we are human being; we may live for many years, hundred years, in comparison to the ant's life, and similarly, we may live hundred years, and Brahmā is living for millions of years. So it does not mean there is no death. Death must be there. One who has taken birth, he must die. The janma-maraṇa. And as soon as you take birth, the all the material conditions, tri-tāpa-yātana—adhyātmika, adhibhautika, adhidaivika—you have to accept. There is no rescue. As soon as you take birth, janma-maraṇa, jarā . . . janma-mṛtyu-jarā-vyādhi (BG 13.9). As soon as you take birth, then you have to take jarā, old age; and vyādhi, and disease; and last, maraṇa.
So we do not understand this. This is called ignorance, foolishness.
