Musar על מנחות 86:9

I have come, further, to awaken ourselves to [the significance of] something we say every day in the section of tzitzith (Bamidbar 15:39): "And you shall see it, and you shall remember all the mitzvoth of the L-rd." Our Rabbis of blessed memory have said concerning this (Menachoth 43b): "Seeing leads to remembering and remembering leads to doing." But when is this of avail? When he studies and knows the mitzvoth but is afraid that he might forget them. Tzitzith avails for this, that he will remember them and not forget them, and, as a matter of course, he will come to fulfill them. But if he does not know the mitzvoth, how will tzitzith avail him? Therefore, it is very desirable that one learn all of the book, Mitzvoth Hashem, or, at least, Kitzur Sefer Charedim which is included in Zichru Torath Mosheh of the Chayeh Adam. He will thereby know the mitzvoth and will fulfill correctly the mitzvah of tzitzith.
