cover up

I would imagine that those who recite the 13 ikkarim every day assume that just like "adam nifal k'fi p'ulosav" (as the Chinuch writes many places), so too, by  saying the words if the ikkarim again and again it will inculcate those beliefs.  However, in R' Baruch Sorotzkin's sefer on chumash he says the opposite -- reciting the words without first fully believing in the ikkarim inculcates the midah of sheker.  Interesting.

He has a very nice pshat in what it means that Adam discovering his nakedness after the sin of eitz ha'daas.  Why does the Torah single this out? B'shlama if the Torah had told me that after eating the eitz ha'daas Adam now understood quantum mechanics, neicha, but how big an IQ do you need to know you are naked?  

No one who is already wearing clothes says, "I'm naked and need something to cover myself up."  The person understands that they are their body, and the clothes are a separate covering, and so you don't need a covering to the covering.

Before the sin of eitz ha'daas Adam identified who he was as a neshoma.  The physical body was just a covering for the true self.  M'meila, there was no need for clothes because you don't need a covering on top of a covering.

After the sin of eitz ha'daas, Adam's perspective switched and he identified his true self as the guf.  If the guf is the self, then the guf needs a covering, and so he discovered his nakedness.
