"and passing it on to your son"

Why, on Passover, is there importance in the tradition of "and passing it on to your son," and what is the spiritual meaning of this tradition? 

In spirituality, the meaning of "children" are man's desires and attributes which grow upon the previous state and bring man to his next spiritual level. During Passover, one escapes from the level he is on, which is called "fathers," and escapes from Egypt. All the desire that grew is found in "Katnut" (smallness), only in bestowal. This means that man doesn't use his desire to receive, thus, these desires are called "small children," "sons," and thus especially to them should one tell the story of the exit from Egypt. They are told how one escapes to Katnut, to the level of Bina (Intelligence), to the level of bestowal for the sake of bestowal, which is also called "love of benevolence."

Passing it on to your son is called that we "tell our sons" that each new level grew out of the desire to receive. When I run away from this evil, when I do not use it, that is the story of the exit of Egypt. Thus it is also called "order, arrangement."
