So God is the supreme spirit. If you individually study this individual spirit, as you are, I am... We must know, because we are sparks, God is the original fire. We are sparks. Qualitatively the spark and the fire the same thing. The spark is very minute, small, and the big fire is very great. But this... You can study by studying yourself, that because I am spirit soul, I have entered into this lump of matter, therefore this body has developed, this body is moving, the body is working, it is so important, Mr. Such-and-such professor's body or scientist's body. But as soon as that spiritual spark is over, it is nothing but a lump of matter; you can kick it out.
So God is everywhere; simply we have to make our these blunt eyes... Just like education. I am seeing a motorcar, but a advanced motor engineer, he sees also the car, the difference of seeing. If there is some defect in the car, I cannot do it. But one engineer, one who knows, a mechanic, he knows, immediately touches and the car runs. Similarly, we should know that by education, by culture, by knowledge we can understand God, not by fictitious, by concoction, "Oh, I accept this God. I accept that God."
So that education can be very quickly done. Otherwise it is very difficult to understand God. There are so many philosophers in the world, so many scientists, they are declining. Because they could not find what is God, they are denying. Just like my inefficiency of my eyes, I see that beyond this wall I cannot see. I say, "Oh, there is nothing beyond this wall." But I (indistinct). That is my lack of education. Not that there is nothing beyond this wall. My imperfect eyes cannot see, my imperfect senses cannot realize. But you can make your senses perfect to see God by a process. What is that? Bhakti-yoga.
That is explained by Kṛṣṇa in the Bhagavad-gītā, bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ (BG 18.55). In one place Kṛṣṇa has said, manuṣyāṇāṁ sahasreṣu kaścid yatati siddhaye (BG 7.3) = "Out of many millions of persons, one is very much anxious to make his life perfect." Everyone is not. They are simply working like cats and dogs. That's all. Nobody is interested how to make life perfect.
Manuṣyāṇāṁ sahasreṣu, out of millions of person, one becomes interested how to make this life perfect. Manuṣyāṇāṁ sahasreṣu kaścid yatati siddhaye, yatatām api siddhānām (BG 7.3), and out of many such perfect person who has made his life perfect, out of many such person, kaścid jana..., kaścit vetti māṁ tattvataḥ, knows God.
