The atheist class, they do not approach. They say: "Why shall I approach God? I shall create my wealth, by advancement of science, I shall be happy." They are duṣkṛtinaḥ, most sinful, one who says like that, that: "For my prosperity, I shall depend on my own strength, my own knowledge." They are duṣkṛtinaḥ. But one who thinks that "My prosperity depends on the mercy of God," they're pious. They're pious. Because, after all, without sanction of God, nothing can be achieved. That's a fact. Tāvad tanur idaṁ tanūpekṣitānām(?). That is also statement of That we have discovered so many counter-acting methods for diminishing our distressed condition, but if it is not sanctioned by God, these counteracting proposition will fail.
The example is... Just like you have discovered nice medicine, very qualified physician. That's all right. But when a man is sick, ask the physician: "Can you guarantee the life of this patient?" He'll never say: "No, I can do so. I cannot do that. I try my best. That's all." That means the sanction is in the hand of God. "I am simply instrument. If God does not like that you should live, then all my medicines, all my scientific knowledge, medical knowledge, will fail." The ultimate sanction is Kṛṣṇa's. They, the foolish persons, they do not know. They are, they are, therefore they are called mūḍha, rascals. That whatever you are doing, that is very good, but, ultimately, if it is not sanctioned by God, by Kṛṣṇa, this will be all failure. They do not know that. Therefore they are mūḍhas. And a devotee knows that: "Whatever intelligence, I have got, I may try to become happy, if Kṛṣṇa does not sanction, I'll never be happy." This is the distinction between devotee and nondevotee.
So Kṛṣṇa says that: "Anyone who is trying to approach Me, to become Kṛṣṇa conscious, at the same time, he wants to become materially happy, he's not very intelligent." That means he's wasting his time. Our main business is how to become Kṛṣṇa conscious. This is the main business of human life. But if we waste our time for material improvement, and forget chanting, then that is loss, great loss. So such mentality, Kṛṣṇa says: āmi vijña ei mūrkhe viṣaya kene diba. "So this rascal is asking some material prosperity from Me by discharging devotional service. Why shall I give him material prosperity? Rather, whatever he has got, I shall take it away." Yes. (laughter) It is not laughing. When it is taken away, we become very morose. But that is the test. That is stated by Kṛṣṇa Himself to Yudhiṣṭhira Mahārāja: yasyāham anugṛhṇāmi hariṣye tad dhanaṁ śanaiḥ (SB 10.88.8).
