Well, it is Chodesh Nissan here in Yerushalayim, so here is a vort on the hagadda.
Since it is Alef nissan here, this dvar torah will be given L’iluy Nishmas Yaakov ben Reuven Tzvi (the grandfather of Moderator-72, the backbone and brains behind this wonderful Makom Torah)
Rav Shach asks “Something seems weird about the answer the father gives to his Chachom son. It seems the Chachom is asking about the ta’amei hamitzva (reason behind the mitzva) yet the father answers with halachos about this mitzva. How does this make sense?”
Rav Shach explains that a great lesson is being taught here, and this is the essence of “???? ?????”. One who strives to learn the reason initially, will do so to arrive at questions in order to invalidate the commandments and the one commanding them. One should first start with the mitzvos, and learn about them as they are doing them properly.
This is the answer to the Chacham. If you want to know the reason for doing the mitzvos first you need to do them properly and with the proper d’vakus. Only then can you correctly understand the reason for them.
