When you go to primary school the teacher, in the beginning, controls all such things as sitting in the room, speaking, and every conduct. All of his statements are "do nots." Through this, no matter what you may become after a university or doctor course, you can be a person of large caliber. Wherever you go and settle down you can be a master there. You prepare that from primary school. Therefore, all of its teachings contain "don'ts." You like to run about, jump over the fence, and kick the door as you want at rapid speed. But you are always told "don't." This is true of our Kwon Jin. Mother gave him advice: "You must stay here. Don't get into mischief outside." He is, however, trying to rush out into the street early in the morning whenever his mom and dad aren't around him. So there must always be "don'ts" for him.

You should know this. Therefore, making this instructional material.... God never uses good and sweet baits in fishing. He always puts restrictions on us with various "don'ts." You are apt to become dirty every moment wherever you go in the fallen world. Therefore He cannot let you do as you wish, but tells you, "Do only this in this way." All He can say is, "Jump high. Jump high", to let your neck be hooked by Him. (136-209)

Which teacher do you like in your school? One says, "Hey, guys. You don't like to study on this beautiful day. Why don't you go out and play in the field of flowers?" And the other says, "You rascals, Spring day? By no means. Study! Study!" Which teacher is better? [The latter] (131-117)

In your school, which is the good teacher, the teacher who strictly teaches you, with a piece of chalk, making his eyes glare, or the teacher who takes it idly and easily in his teaching? Who is the good teacher? [The strict teacher] You know it. Therefore, in your school, the strict teacher is a good teacher. Do you understand? If you obey him and digest his teaching, even if he uses abusive language, you can take your share in that class. Through the sharing in that class you can become a direct disciple of the teacher. That is the principle. Is it or not? [Yes, it is] That is the principle. (161-37, 125-82)

The teacher should give the students deep love. Students absolutely obey the teacher who is giving them deep love. Are the students of today the ones who make the grade, or flunkers? [Flunkers] They are terrible flunkers. They cannot be pardoned.... God loves us; therefore, let the universe be all obedience! (164-50)
