Two arrangements of the four passages of the Tefilin
Synopsis
The Tefilin are said to be the Mochin, and Rabbi Shimon describes all the parts of the phylacteries and their meaning in terms of the Sfirot and the Holy Names of God and the letters of the alphabet. Lastly Rabbi Shimon tells us what Rabbi Akiva had to say about the flowing light that is never interrupted and that comes from Infinity.
