So guru's business is to bring out the disciples from darkness to light. That is guru's business. That is guru. First business is that because he is suf . . . everyone is suffering on account of ignorance. Just like you contaminate some disease out of ignorance. You do not know hygienic principle; you do not know that, "This thing will contaminate me. This association will contaminate me. This kind of food will contaminate me." Because we do not know, therefore we contact infection, sometimes suffer from disease. It is very simple to understand. Everyone's . . . suppose one commits something criminal due to ignorance. Due to ignorance. But in the court, when a man is criminal, in the court, if he says, the criminal, if he says that, "I did not know the law," he'll not be excused. Ignorance is no excuse. 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 cannot 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.
Therefore guru's business is . . . every human being is suffering in this material world. Nobody can say that, "I am not suffering." It is not possible. There must be suffering. There are three kinds of sufferings. That out of ignorance also, a rascal is suffering, he's saying that, "I am very happy." That is also another ignorance. There are three kinds of sufferings in this material world: ādhyātmika, ādhibhautika, ādhidaivika. Suffering on account of my own body and mind—this suffering is not imposed by anyone else. I do it. The same thing, that I cannot digest but I eat more, so there must be dysentery. You must suffer. This is due to mind, body and mind. That is another one kind of suffering. Another suffering is imposed by other living entities. Just like your enemy or an animal—or there are ants, mosquitoes, flies, they are all causing suffering. You are killing them, and they are trying to give you suffering. This is called struggle. This is called ādhibhautika, suffering given by other living entities. Suffering caused by myself, this is called ādhyātmika. And suffering caused by other living . . . and there are other sufferings, caused by the nature, superior power, ādhidaivika. All of a sudden, there is no rain, no rainfall, and now for want of rainfall there is no food grain. Excessive heat, excessive chilly cold, earthquake, famine . . . so many, by natures, imposed by the natures. Flood.
