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 Bhushan Vaddery, 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, there . . . 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. How 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 arcā-vigraha.
Prabhupāda: Of course that's nice, but then you are following blindly your spiritual master. What is your experience?
Devotee (2): Your heart becomes pure.
Prabhupāda: Hmm.
Devotee (3): 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 (4): We cannot see Kṛṣṇa, because our eyes are impure . . .
Prabhupāda: Then you are following blindly.
Devotee (4): But by following the scriptures and the śāstras we get pure.
Prabhupāda: Yes. Feeling. That is anubhava. Anubhava ananta svarupa, parameśvara. That is the and then . . . (indistinct) . . . you can feel His presence. That is being explained here (reads Sanskrit commentary)
This very simple. Prahlāda Mahārāja saying that as the expert gold miner, when he sees there are gold particles in the field, naturally he concludes . . . still, in India there is a river, in that river gold particles, in the water gold particles can be found. Gold particles. Many poor men, they whole day work and strain the water in different way and get some little gold, still.
So, by the symptoms, by the symptoms the expert gold miner finds out that, "Here is gold, gold mine." Because in the within the soil, or with the soil you find some gold particles. That is the way, here it is said. Similarly, one can find out Kṛṣṇa by the symptom, the characteristics, of this world.
There are common sense. Just in everything there is a controller, there is a life. Just like in my body, I am controlling this body, and there is living force, living symptoms. Similarly, this whole world which is going on, there are so many things that are that is . . . that requires nice brain. This planetary system is moving nicely, exactly to the order. So one should consider that there must be some brain behind this—how things are going so nicely. That is common sense.
Just like the gold mine expert, as soon as he finds some gold particles either in the vicinity, water or land, they consider there is gold mine. Similarly, when you find that things are going on so nicely, there is a big brain behind this. That is the statement of Professor Einstein. He also says that as we make progress and we see wonderful things, we are bound to believe that there is a big brain. There is a big brain.
(reads Sanskrit commentary) So as the poor man goes to the riverside and by straining the water by—their specific process—they find out some gold; similarly, a person, kṣetreṣu deheṣu ātma adhyātma-vid brahma-gatiṁ labheta. This meditation means thinking very deeply, "What I am? What I am?" And the process of the yoga system is the same system as you strain water and find out gold—similarly, if you follow the yoga system, dhyāna, dhāraṇa, āsana, prāṇāyāma—that is mechanical—then you will find that "I am the spirit soul, and there is Supreme Soul, Kṛṣṇa."
That is possible. That is really perfection of yoga practice. Not that simply pressing the nose. No. Actually perfection of yogic meditation is to understand the self; the soul is there and the Supersoul is there. The process is there.
