Those who are rascals, fools, if you speak something valuable for his life he'll not hear you; he will become angry. The example is given, payaḥ-pānaṁ bhujaṅgānāṁ kevalaṁ viṣa-vardhanam. Just like if a snake, if you ask the snake that "I shall give you daily a cup of milk. Do not commit this harmful life, biting unnecessarily others. You come here, take a cup of milk and live peacefully," that he will not be able. He . . . By drinking, by drinking that cup of milk, his poison will increase, and as soon as the poison is increased—it is also another itching sensation—he wants to bite. He'll bite. So the result will be payaḥ-pānaṁ bhujaṅgānāṁ kevalaṁ viṣa-vardhanam. The more they starve, that is good for them, because the poison will not increase. The nature's law is there.
And as soon as one sees a snake, immediately everyone becomes alert to kill the snake. And by nature's law . . . It is said, "Even a great saintly person, he does not lament when a snake is killed." Modeta sādhur api sarpa . . . vṛścika-sarpa-hatyā (SB 7.9.14). Prahlāda Mahārāja said. When his father was killed and Nṛsiṁha-deva was still angry, so he pacified Lord Nṛsiṁha, "Sir, now You can give up Your anger because nobody is unhappy on account of my father being killed." Means, "I am also not unhappy. I am also happy, because my father was just like a snake and a scorpion. So even a great saintly person is happy when a scorpion or a snake is killed." They are not happy if somebody is killed. Even an ant is killed, a saintly person is unhappy. But a saintly person, when he sees that a snake is killed, he is happy. He is happy.
So we should not follow the life of a snake, pravṛtti-mārga. Human life is meant for nivṛtti-mārga. We have got so many bad habits. To give up these bad habits, that is human life. If we cannot do that, then we are not making any spiritual progress of life. Spiritual progress . . . So long you will have a little desire for committing sinful life for your sense gratification, you will have to accept a next body. And as soon as you accept a material body, then you will suffer. Yena.
It is said that nūnaṁ pramattaḥ kurute vikarma (SB 5.5.4). These rascals, they are mad. They are committing sinful life simply for sense gratification. There is no need of committing sinful life, but for sense gratification they are doing that. So Ṛṣabhadeva says, "It is not good, because for sense gratification you have got already this body, and you know, experiencing, that you are suffering threefold miseries, and again you are committing something which will oblige you to accept another body. This is not good. This is not good." We should do in such a way that we may not accept again this material body. That will save us from all suffering.
