Kabbalah su Neemia 9:63

Now, the pure soul, which is compared to the fruit, consists of 613 organs and veins and resides within the 613 organs and veins of the impure soul, which is compared to the shell (Kelipah) covering over the fruit. In turn, they both reside within the 613 organs and veins of the body. Thus, the organs of the pure soul reside within the organs of the evil soul and the organs of the evil soul reside within the organs of the body. In order to exist, each of these two souls needs spiritual sustenance. However, the spiritual sustenance of the holy soul is drawn to it through the fulfillment of the Torah, which consists of 613 mitzvoth, corresponding to the 613 organs of the soul. Thus the Torah is called “bread”, as in the verse¹⁵Proverbs 9:5, “Come, partake of My bread”. Each of the 248 organs receives sustenance from a specific mitzvah that relates to that organ. However, if a person lacks the fulfillment of any mitzvah, the organ specific to that mitzvah will lack the sustenance drawn to it from the four letters of HaShem. This is indicated by the verse¹⁶Nehemiah 9:6, “You (HaShem) give life to all.” All the mitzvoth depend on these four letters, as our sages of blessed memory said, “The letters Yud (י) Hey (ה) coupled with the word, “My name” (שמי) of the verse, “This is My name and this is My memorial (זה שמי וזה זכרי) have the numerical value of 365. The letters Vav (ו) Hey (ה) coupled with the word, “My memorial” (זכרי) of the same verse, have the numerical value of 248.”

Thus, Aleph-Tav (E"T) includes all the letters from beginning to end. Afterwards, the letter Hei was added to E"T, so all the letters would be united with Hei. This formed the word 'you' (Aleph-Tav-Hei) Thus, the verse reads: "And you do preserve them all". E"T is the secret of Adonai and is so called. Heaven is Yud-Hei Vav-Hei, which is superior to the name Adonai, for Zeir Anpin, called "the heavens" and also called "voice," is the secret of the name of Yud-Hei Vav-Hei. And his Female principle, called 'E"T' and 'speech,' is the secret of the name Adonai.

According to this secret, the Holy One, blessed be He, is called "a great El, mighty and terrible." - הָאֵל הַגָּדוֹל הַגִּבּוֹר וְהַנּוֹרָא. These names are engraved above by the secret of the upper Chariot, which comprises four letters of the name Yud Hei Vav Hei, which is a name that includes all the other names. The combining of the lower ox within the upper lion is equivalent to the letter Yud of Yud Hei Vav Hei, and is the secret of the name El. The combining of the lower lion within the upper ox is equivalent to the letter Hei and is the secret of the name Mighty. The combining of the lower eagle within the upper lion is equivalent to the letter Vav and is the secret of the name Great. And the face of a man of above, which includes all the living creatures from below that have ascended to it, is equivalent to the lower Hei of Yud Hei Vav Hei and is the secret of the name Terrible. These images, the ox, eagle, lion and man, are engraved and carved on the throne, which is the Female principle of Zeir Anpin, and the throne is carved and decorated by them. And these likenesses were embroidered on the throne: one on the right, one on the left, one on the front and one on the back, thus corresponding to the four directions of the world. The face of the lion is imprinted on the right, which is the south wind; the face of the ox on the left, which is the north wind; the face of the eagle on the front, which is the east wind; and the face of a man on the back, which is the west wind. This is the secret of the four letters of Yud Hei Vav Hei.
