Just like in darkness, ajñāna-timirāndhasya. Ajñāna means ignorance, without knowledge. That is called ajñāna. So ajñāna is compared..., ignorance, stupidity, is compared with darkness. Just like if you are, if this room, immediately, all lights are off, then it becomes dark. We cannot see where I am sitting, where others are sitting. It becomes a confusion. Similarly, in this material world, we are all in the darkness. This material world is called darkness. It is called tamaḥ. Tamaḥ means darkness. Or timir. Timir means darkness. And actually, it is darkness. Because, because this material world is dark, there is need of sunlight, there is need of moonlight, there is need of electricity. (aside:) This child disturbing.

Similarly, even a child, he does not know, he catches on fire—the fire will burn. No excuse. The fire will not consider that "Here is a child. He does not know. Excuse." No. No excuse. So as there are stringent laws of nature or laws of the state, that because you do not know something, you have committed some wrong, you'll be excused—no, that is no, there is no possibility. You have committed something wrong out of ignorance, you must suffer. This is the law nature's law. You cannot... I have (given) many examples. Suppose you can not eat more. Out of ignorance, if you eat more, then you have to fast two days, three days, suffering, or you'll have some disease. You cannot violate any laws of the nature or any laws of the state anywhere. Wherever there is law, if you break it, then you'll suffer. This is ignorance.
