By doing this we arouse the imagination in order that it will become fixed in our minds forever. Rabbi Shmuel Rozovsky, the Rosh Yeshivah of Ponovez, added to these words of the Sefer Hachinuch. Although the Passover sacrifice is no longer conducted as it was in the time of the Temple, its content and meaning continues to be applicable at all times and in every moment. It is obligatory upon every Jewish person to conduct himself with great dignity, as befits the ways of the children of kings. Everything has a value and a significance.
Every movement has a meaning.
Conduct like that can become a vacuum into which all of a person's spirituality can disappear. For example, a Torah student can learn diligently and properly throughout the seder. Then he goes to the cafeteria to eat. If he does not conduct himself properly during the meal, G-d forbid, then there can be formed a vacuum which will swallow everything that he acquired and achieved during his learning. Everything can fall into the vacuum, G-d forbid.
