Although there is a strict order in the above and below relationship of parents and children, when it centers upon love, it is not a problem if the vertical order changes to a horizontal order. Isn't that so? The basic rules are that the father should order his son, but when the son calls, "Father, please come here," he cannot but go. Even if a two-year-old daughter calls, "Daddy, come here," he has to go. Even if this position is a point where the vertical standards change horizontally, there would be no contradiction or collision. We can praise this precious standard, as this standard of happiness is made only by love. (49-54)

Parents concentrate only on raising their children until they grow up. The more children grow, the more they stand in an object position to their parents. Isn't that right? That is normal. If a child grows up, would he still think, "Oh, it is best to stay in my parent's arms and drink my mother's milk"? He must work. The above and below relationship changes to an object-partner relationship. (42-110)

The reason parents are noble is because they live for the sake of the children. That is why the position changes later. Old parents are like young children. When the children were young, the parents were their teachers, but when they become 70 or 80, they are like children. Then, the children must stand as the parents. The children must love their parents in turn, since their parents raised them. That is the Principle of heaven and earth.

Similarly in the family, when the parents are wrong, the children must correct them and vice versa. They should complete the common purpose.

When the children are young the parents govern them, but when the parents grow old, sons and daughters govern their fathers and mothers. Is this true or not? (It is true) The principle of heaven and earth is like that.
