Ten White Radiancies, Ten Sefirot: These Above Those
“Ten סְפִירוּת בְּלִי-מָה (sefirot belimah), numerals of nothingness. Their measure is ten, yet infinite” (Sefer Yetsirah 1:1).
“You shall surely tithe all the yield of your seed that comes out in the field year after year (Deuteronomy 14:22)—at all times you must reckon each of the rungs, ‘Ten and not nine, ten and not eleven’ (Sefer Yetsirah 1:4). Another explanation: עַשֵּׂר תְּעַשֵּׂר (Aser ta’aser), You shall surely tithe [lit., tithe you will tithe]. Why two times? Because here there is a deep and hidden mystery which the mouth cannot speak nor the ear hear. You already know that tithe alludes to ten lower [sefirot]. Until here I have permission to explain. If you are one of the enlightened, you will understand this great mystery with your fullest intellectual capacity and will surely not let it out of your mouth: Here below we give our tithes according to the supernal model—so that man imitate his Creator” (Rabbi David ben Yehudah ha-Ḥasid, The Book of Mirrors, 236:29-237:3, adapted from Matt, Sefer Mar’ot Ha-Zove’ot, p. 26, cf. Tiqqunei ha-Zohar 31a-b).
“The things hidden are for YHWH our God and things revealed for us and for our children forever (Deuteronomy 29:28). Understand this verse by its inner sense, deep and sealed though it may be. For YHWH—the Cause of Causes, for all proclaim that they are His; each of the עֶשֶׂר צַחְצָחוֹת (eser tsaḥtsaḥot), ten white radiancies, that comprise אֲרִיך אַנְפִּין (Arikh Anpin), Elongated Countenance, form ten inner rungs. And for our children—ten that parallel ten rungs within supernal Keter who are not revealed but remain concealed and hidden, imperceptible to the inquirer. For they belong to the Cause of Causes, blessed be the glory of His name and His majesty forever. Therefore, the enlightened will understand and will remain silent for God, and he alone will see wonders from the holy Torah He gave us from His very own treasury” (Rabbi David ben Yehudah ha-Ḥasid, The Book of Mirrors, 252, adapted from Idel, “The Image of Man Above the Sefirot: R. David ben Yehuda he-Ḥasid’s theosophy of ten supernal ‘ṣaḥṣaḥot’ and its reverberations.” Kabbalah: Journal for the Study of Jewish Mystical Texts 20  p. 181-212).
“Come and see: How many hidden causes are enclothed and conveyed by the sefirot! The sefirot are but chariots to them, for they are concealed from human thought. Of them is written: For he who is high has a higher one watching him, and still higher ones over them (Ecclesiastes 5:7)—נְהוֹרִין מְצוּחְצָחִין (nehorin metsuḥtsaḥin), glaring white lights, these above those, but those that are receptacles are darkness compared to the others above them. And their is no light that can exist before עִלַּת הָעִלּוֹת (Illat ha-Illot), the Cause of Causes, all lights are darkened before Him” (Zohar 1:23a, Tiqqunei ha-Zohar).
Your wonder known in the darkness, Your bounty in the land of נְשִׁיָּה (neshiyah), oblivion (Psalms 88:13).
“בֶּן-מְנַשֶּׁה (Ben Menasheh), son of Manasseh (Numbers 27:1)—the Cause of Causes who is called מְנַשֶּׁה (Menasheh), Forgetting. Why is the Cause of Causes called Forgetting? Because He is a place to which forgetting and נִשָׁיוֹן (nishayon), oblivion, pertain, as in the expression כִּי-נַשַּׁנִי אֱלֹהִים (ki nashani Elohim), For God has made me forget (Genesis 41:51).
Why? Because concerning all the rungs and causes one should search for their reality from the depth of supernal Ḥokhmah. From there it is possible to understand one thing from another. However, concerning the Cause of Causes there are no sides anywhere to search, to probe; nothing can be known of Him; for He is hidden and concealed in the mystery of הַאַיִן וְהַאֶפֶס (ha-Ayin ve-ha-Efes), Nothingness and Naught.
Therefore forgetting pertains to Him, as regards comprehension of this place. So open your eyes and see this great and awesome mystery. Happy is he whose eyes shine from this mystery, in this world and the world that is coming” (Rabbi David ben Yehudah ha-Ḥasid, The Book of Mirrors, 227:15-23, translated in Matt, Sefer Mar’ot Ha-Zove’ot, p. 21-22).
