This body is not false. Not only this body; everything material. We don't take it is false. We take it as temporary. And temporary, how it should be utilized for our best purpose? Just like the mail passengers in the train, they are using the half an hour time for taking bath, utilize. Similarly, although this body is temporary, we can utilize it for the best purpose. What is that best purpose? Realization of Kṛṣṇa. If we can utilize this temporary body for utilization . . . for understanding Kṛṣṇa consciousness and be fixed up in that Kṛṣṇa consciousness, that is the best use of the bad bargain.
So Prahlāda Mahārāja therefore says in this verse, prāṇaṁ punāti sa-kulam (SB 7.9.10). One who has engaged himself in Kṛṣṇa consciousness, aravinda-nābha pādāravinda, lotus feet of Kṛṣṇa or Viṣṇu, he purifies himself as well as his family. Purifies his whole family. Sometimes a Vaiṣṇava born in a village, he purifies the whole village. These are statement in authentic scriptures.
So apart from village, a Vaiṣṇava born in a family can give the best service to his family, because he purifies. Sa-kulam. The host of his ancestors and forefathers, everyone is purified. Na tu bhūrimānaḥ. But the person who is simply proud of being born of a brahmin family, and even if he has all the good qualities of a brahmin, but if he's simply proud, he has not engaged his qualification in understanding Kṛṣṇa consciousness, Prahlāda Mahārāja says that he is useless.
