Halakhah for Pesachim 55:6

And they, may their memory be blessed, already informed us (Sanhedrin 21b) why we do not know the reason for all of the commandments; and they said that the thing is that it not become a stumbling block for us. And they brought a proof, as behold, the reason for three of them was revealed, and a great man of the world stumbled upon them. And let not a quibbler think to come against me with the metaphor that they, may their memory be blessed, said (Pesachim 28a), "The spoon carved by the carpenter will burn his mouth with mustard," about that which I said now: That God, may He be blessed, hid the reasons from the commandments from us, and [yet] I have raised my hand to speak about them to my youth. As my teachers have already preceded me to speak several things about them in the Midrashim and in other places, by way of their simple understanding. And the depth of their wisdom, the strength of their understanding and their great holiness is stored in them - and even all the winds of the world cannot move them. And [regarding] anyone who is [able to] deepen counsel in their simple understanding, because he longs to 'peer through the lattice,' to delight in the splendor of their vision and to gather from their leaves to gird himself with them - it is not fit to place blame upon him, but to bless him and to mention him for praise, 'in that he is there.'
