Prabhupāda: And just like one can understand from the characteristics of the particular soil, that there is gold. In this (place) there is possibility of gold. That is agronomist?
Devotee: No, that would be geologist.
Prabhupāda: Geologist?
Devotee: Yes.
Prabhupāda: All right, geologist. (laughter) So.... I don't think geologist. (laughter) Geologist is different. You have no dictionary? Where is my dictionary?
Devotee: It is in the next room. Should I get it?
Prabhupāda: All right, we shall see later on. Take it for agronomist, geologist. But soil expert (laughter). Soil expert to... He knows how to find out a particular type of mine. They can find out, "Here there is mica, in this soil there is coal, in this soil there is gold." So Prahlāda Mahārāja is giving very nice example that, svarṇaṁ yathā grāvasu hema-kāraḥ. Hema-kāraḥ means goldsmith, not goldsmith. Goldsmith is manufacturer of gold ornaments. Hema-kāraḥ means gold expert, you can say. He can find out in the soil where there is gold mine. Still there are. I know when I was managing Dr. Bose's laboratory, one chemist, Chandra Bhusan Vadery (?), he was a well known chemist in Calcutta. So, one Marwari gentleman was after him. He said that "I know how to find out gold mine." So, the Marwari gentleman spent after him lakhs of rupees and he said that "Here there is gold," but unfortunately gold was not found. (chuckles) And the gentleman lost so much money. So, but there are experts otherwise how gold mines are found out? There are experts. So here it is said... It is not new thing. Prahlāda Mahārāja said that this art is known millions and millions of years ago. It is not that the modern science has discovered airplane, modern science has discovered how to go to other planet and they have mining industry, no. These are all known. There is no question of modern science. Now, otherwise how Prahlāda Mahārāja gave this example? Vivikta, viviktatma jnana, jnani napi bhavena brahmata praktikasam syat (?).
Question may be put by opposing party that simply by becoming Kṛṣṇa conscious how one can know God? What will be your answer? What will be your answer? Suppose an opposing party says that "All right, I accept that you are Kṛṣṇa conscious or God conscious, you have devoted your life for Kṛṣṇa, so how do you find, how do you see Kṛṣṇa that you are working for Him?" What will be the answer? Are you following blindly or you have experience of Kṛṣṇa? Yes. What will be the answer? It's a very intelligent question. People will ask you, perhaps they ask, "Have you seen Kṛṣṇa?" "Why you are Kṛṣṇa conscious?" What is your answer?
Devotee: You see Him through śāstra and the teachings of the spiritual master and His arca-vigraha.
Prabhupāda: Of course that's nice, but then you are following blindly your spiritual master. What is your experience?
Devotee: Your heart becomes pure.
Prabhupāda: Hm.
Devotee: First you can hear Kṛṣṇa before you see Him and this is a purification process. And the purification process can be felt and then you ask the person, "You can feel it yourself by chanting Hare Kṛṣṇa, why not try it?"
Prabhupāda: That's all right, you have tried, whether you have seen? That is the question. You have tried for the last four or five years, whether you have seen Kṛṣṇa?
Devotee: We cannot see Kṛṣṇa because our eyes are impure...
Prabhupāda: Then you are following blindly.
Devotee: (indistinct) the scriptures and the śāstras we get pure.
Prabhupāda: He has feeling. That is (indistinct). Anubhava ananta svarupa, parameśvara. That is the (indistinct). You can feel His presence, that is being explained here. (reads Sanskrit commentary) It is very simple. Prahlāda Mahārāja is saying that as the expert gold miner, when he sees there are gold particles in the field, naturally he concludes....
