Prabhupāda: Why people are getting superior and inferior types of bodies? That is explained, kāraṇaṁ guṇa-saṅgo 'sya sad-asad-yoni-janmasu (BG 13.22). Sad-asad—good and bad, first-class and third-class. Sad-asad-janma-yonisu. Species of life, they are getting. The reason is, kāraṇaṁ guṇa-saṅgo 'sya. Because he's associating with different modes of nature. There are three modes of nature—goodness, passion, and ignorance. So if you associate with goodness, you get one type of body. If you associate with passion, you get another type of body. If you associate with ignorance, you get another type of body. This is law of nature and the witness is the Supreme Personality of Godhead. So there is exactly everything in order. You cannot escape that. Divī hy eṣā guṇa-mayī mama māyā duratyayā (BG 7.14). It is not possible to escape. This is karmavāda. But this karmavāda, just like one man is sentenced by the law to be hanged, nobody can save him, but still there is King's mercy, he can save you.
Guest: (indistinct)
Prabhupāda: Yes.
Guest: (indistinct) so that he can purify himself...
Prabhupāda: Well, that... Just like a child when he's crawling, he touches a fire and he's burned. He forgets. But when he's grown-up, if he inquires from the parents, "Why this scar is in my hand?" The father reminds, "My dear child, you did like this." So because you have forgotten, that does not mean it did not take place. You have forgotten, you do not know, what you were doing at this time yesterday. You are so forgetful. So your remembering or forgetful doesn't matter. The law of nature must work severely. It doesn't matter whether you forget or you do not know the law. Forgetfulness of law is no excuse. You must suffer. Just like the child when he touches the fire, the fire does not consider, "Oh here is an innocent child, why should I burn him?" He must be burned. That is law of karma. When you touch fire it must act and you must suffer. Without any judgement the law is already there.
