ייִדישער מחשבֿה אויף דברים 6:8

Let one learn from what G-d has commanded a king (of Israel) in saying: "And it will be, when he sits upon his royal throne, that he shall write for himself this Torah on a scroll...And it shall be with him always, and he shall read it all the days of his life [so that he may learn to fear the L-ord, his G-d, to keep all the words of this Torah and these statutes, to do them]" (Devarim 17:18), and "This book of the Torah shall not leave your mouth; you shall meditate therein day and night [in order that you observe to do all that is written in it, for then will you succeed in all your ways and then will you prosper]" (Yehoshua 1:8). And also (to every Jew in the Shema): "And these words, which I command you this day, shall be on your heart" (Devarim 6:6), and "you shall bind them for a sign upon your hand, and they shall be Totafos between your eyes" (Devarim 6:8). And He reinforced the matter in the chapter of Tzitzit in saying: "this shall be Tzitzit for you, and when you see it, you will remember all the commandments of the L-ord to perform them, and you shall not wander after your hearts and after your eyes after which you go astray" (Bamidbar 15:39), and then "So that you shall remember and perform all My commandments and you shall be holy to your G-d" (Bamidbar 15:40).

The 5 physical: (1) You shall teach them to your children. (2) You shall speak in them (3) You shall bind them as a sign on your hand (4) They shall be as Totafot between your eyes. (5) You shall write them upon the doorposts of your house and upon your gates.

THE precepts of the ninth class are those enumerated in the Section on Love. Their reason is obvious. The actions prescribed by them serve to remind us continually of God, and of our duty to fear and to love Him, to keep all His commandments, and to believe concerning God that which every religious person must believe. This class includes the laws of Prayer, Reading of Shema, Grace, and duties connected with these, Blessing of the priests, Tefillin, Mezuzah, Ẓiẓit, acquiring a scroll of the Law, and reading in it at certain times. The performance of all these precepts inculcates into our heart useful lessons. All this is clear, and a further explanation is superfluous, as being a mere repetition and nothing else.
