So labhante brahma-nirvāṇam ṛṣayaḥ kṣīṇa-kalmaṣāḥ. Just like by decreasing temperature we come to the path of healthy life, similarly, if we decrease our sensual activities... The material life means sensual activities, nothing more. Whatever advancement of civilization we are creating, that means we are simply creating artificial sense enjoyment. That's all. This is called material civilization, simply sense enjoyment, nothing more. So we have to... Of course, we don't decry the modern civilization, but it has its proper use. Just like we are also using here electric light, the microphone, and the tape recorder. This is the gift of the modern science. So instead of decrying them, let them engage in the matter of understanding Kṛṣṇa consciousness. Then everything will be properly utilized. We cannot go back. You cannot go back in the matter of advancement of modern civilization, but here we have got a point, Kṛṣṇa consciousness. Nirbandhaḥ kṛṣṇa-sambandhe. We can engage everything in the matter of understanding Kṛṣṇa consciousness. Everything can be utilized properly. Yuktaṁ vairāgyam ucyate. We haven't got to give them up. Our Gosvāmīs, our predecessors, ācāryas, they do not recommend that whatever is produced we shall not give them up. "Oh, it is all material. We don't want." No. Even if that is material... Material is everything. My body is also material. So as I am utilizing my material body for spiritual advancement, similarly I can utilize anything material for spiritual advancement. That is possible. So that prescription is given, nirbandhaḥ kṛṣṇa-sambandhe. You just try to engage everything in Kṛṣṇa consciousness. Then you'll have... That means everything will be transformed into spiritual. By Kṛṣṇa consciousness everything will be transformed into spiritual. Just like the iron rod, if you put into the fire it gets warm, warmer, and when it is red-hot, then it is no longer iron rod, it is fire, similarly, if we constantly engage all our energy in Kṛṣṇa consciousness, then, even though we have increased the temperature to 107 degrees, that will be transformed into 107 degree of spiritual life. Yes. That is the secret of this Kṛṣṇa consciousness.
As we'll understand when we come to the Ninth Chapter, it is clearly stated that su-sukhaṁ kartum avyayam (BG 9.2). It is very happy to adopt this principle of Kṛṣṇa consciousness. So instead of lamenting what has been done—that is useless. No use lamenting. We have to now go, make progress, advance by Kṛṣṇa consciousness and utilizing everything for that purpose, Kṛṣṇa consciousness. Then everything will be all right.
