The subtle body is mind, intelligence and ego. So if we think of Kṛṣṇa in the mind always, and if we work intelligently for Kṛṣṇa, that is mind and intelligence. And if we change our false ego . . . ego means "I am." So I am at the present moment thinking, "I am American," "I am Indian," "I am white," "I am black," like that. "I am human being," "I am animal," "I am cat" or "dog," so many things, "I am." This "I am" has to be changed. I am eternal servant of Kṛṣṇa.
In this way, if you educate or transfer the activities of the subtle body, mind, intelligence and ego, then, at the time of death, you give up this subtle body, material subtle body, mind, intelligence and ego, and by your spiritual body you go back to home, back to Godhead. This is called Kṛṣṇa consciousness movement. Gross body, automatically we give up.
Now, we should practice to give up the subtle body. To give up this subtle body, one has to develop love for God, prema. And the process is, how to give up the subtle body, ādau śraddhā. First of all śraddhā. Śraddhā means a faith or some respect. Actually it means respect. Just like you have come here out of faith and respect. So "Here they're talking about God. There is temple of God. Let us go there," this is faith and respect. Ādau śraddhā. This is the beginning.
Now, after coming here, when you hear about God . . . because we, our only business is, we don't talk here politics or sociology or anything. That comes automatically as subordinate things, but our business is to talk about God. So those who talks about God, they are called saintly person. There are two kinds of men within this world: materialistic person and transcendentalist, or man interested in spiritualism.
So those who are interested in spiritual life, they talk of self-realization. And those who are materialistic person, they also talk. They talk about this body, how to keep this body nicely. There are politics, sociology, welfare activities, so many things, all concerning to the body. So there are many talks, just like in the newspaper. In your country especially, bunch of newspaper. So many talks, advertisement, fashion, this news, that news, full up.
So the materialistic person, they read the newspaper, but we read Śrīmad-Bhāgavatam. That is the difference. We are also reading; they are also reading. So nṛṇāṁ santi sahasraśaḥ, śrotavyādīni rājendra nṛṇāṁ santi sahasraśaḥ (SB 2.1.2). Śukadeva Gosvāmī said to Parīkṣit Mahārāja, "My dear king, there are many hundreds and thousands of topics for the materialistic person." Sahasraśaḥ. Sahasraśaḥ means thousands. And that is a fact. So many novels, so many fiction, so many so-called philosophy, newspaper, cinema paper, this paper, that paper, so many. Sahasraśaḥ.
