Kleśada. This material body is kleśada. Kleśada means always giving us trouble. Always giving. Kleśada āsa. So one should always remember that "I have got this material body, which is suffering heat, cold, mātrā, sukha, duḥkha, happiness, distress." Why? Because this material body . . .
- mātrā-sparśās tu kaunteya
- śītoṣṇa-sukha-duḥkha-dāḥ
- āgamāpāyino 'nityās
- tāṁs titikṣasva bhārata
- (BG 2.14)
So long you have this material body, bhūmir āpo 'nalo vāyuḥ khaṁ mano buddhiḥ (BG 7.4), then . . . material world means suffering. You cannot avoid suffering. But the endeavor is how to get out of suffering. That is called struggle for existence.
So you cannot get out of it so long you do not stop acceptance of another material body. That is called real liberation, no more accepting material body. Therefore Bhāgavata says that, "These madmen . . ." Nūnaṁ pramattaḥ. Pramattaḥ. Mattaḥ means mad, and pra means prakṛṣṭa-rūpeṇa, sufficiently mad. Nūnaṁ pramattaḥ kurute vikarma (SB 5.5.4). There are karma, vikarma and akarma. So one should know. Vikarma means criminal activities. Just like so many people are acting criminally simply to get money, as if money will save him. If he acts criminally, simply sinful activities, and by such, he is punished to get another body which is sinful, pāpa-yoni, then what is . . . how his money will save him? No, that cannot save. Just like if you have become criminal and you are arrested by the state. Suppose you are millionaires. Your money will save you? No. That will not save. But they . . . for money they are doing all sorts of sinful activities. Nūnaṁ pramattaḥ kurute vikarma yad . . . (SB 5.5.4). Why they are doing? Yad indriya-prīta . . . simply for sense gratification, that's all. Only benefit is sense gratification. Yad indriya-prītaya āpṛṇoti.
Therefore Ṛṣabhadeva, na sādhu manye: "Don't do this. Oh, it is not good." Why not good? Na sādhu manye yato ātmano 'yam asann api. You have got this material body, suffering, although it is temporary, but you have got this. So don't do this. Don't do anything that you get another material body. That is perfection of life. That is Kṛṣṇa consciousness.
