I would dare posit that it’s the ‘tochen’ that counts. These great men were totally into it – at their level – a whole night.
This is the night of chinuch, tradition. Parents to children, Rabbis to pupils. What we put in, stays. Every minute counts. HaShem attached such an importance and significance to these mitzvhos. Indeed, this is Toldos Am Yisroel, our emergence as Yidden. Lets all try to give it our very best, to come out of it as a better Yid.
