As the Communist Party is always disturbing to the government, similarly the demons, the atheist class of men, they're always disturbing to God. How they can gain the benediction from God? They simply disturb Him. And there are different kinds of demons, different class of demons. That is explained in the Bhagavad-gītā. Duṣkṛtinaḥ (BG 7.15). Duṣkṛtina means . . . krti means very intelligent, and . . . what is that word, if a man does something wonderful? Genius? Genius? Yes. So the genius, duṣkṛtina, "Wrong genius." That means the materialistic persons, scientists, they're genius. They have discovered very wonderful machine, wonderful things. They are genius—but duṣkṛtina: not for the welfare of the human's society but for condemning the human society.
Just like the same example, as I have given several times, that . . . the person who has discovered this nuclear weapon, atomic bomb, he's certainly genius. He has got nice brain, that simply egg-like bomb, if you throw, immediately the whole island of Hawaii will be finished.
Just like you dropped your atomic bomb on the other side, Japan, Hiroshima . . . they attacked your Pearl Harbor, and the retaliation was atom bomb on Hiroshima. So these are politics. So this invention of atomic bomb, certainly it requires good brain. But Bhagavad-gītā says that this genius, or this brain, intelligence, has been used . . .
(aside) Stop that.
. . . has been wrongly used.
So the materialistic class of men are undoubtedly very, very intelligent, but their intelligence is being used wrongly. Duṣkṛtinaḥ. Duṣkṛtinaḥ mūḍhāḥ. Mūḍhāḥ. Mūḍhāḥ means rascal, ass. So by their discoveries, by their materialistic activities, atheistic activities, they're simply disturbing. Simply disturbing. That's all. They do not know that, that "I am discovering these material things." If we discuss, we can prolong so many things.
