Jewish Mysticism
Take to heart these instructions with which I charge you this day” (Deut. 6-6). This is the Written Torah, mikra, from the verse “They shall serve you to summon (le mikra) the community” (Num. 10-2), said with respect to the trumpets, for this is the expression of calling (keri’ah) and gathering (asefah). Thus all the Torah is the names of the Holy One, blessed be He. By means of this [Scripture] one reads and draws down the light of the Infinite from above to below.
