Deuteronomio 29:28 Cabala: Or Neerav, Zohar & Tikkunei Zohar

Who has caused these people to chase after the simple meaning [of Scripture] and ignore the esoteric portions? It is you dullards [who] hate knowledge (Prov. 1:23), meaning the knowledge of hidden things. What is written [in the verse] after that? You are indifferent to my rebuke, I will now speak my mind to you. This means that the soul which is enwrapped in the simple meaning [is now addressed]: I will now speak my mind to you and let you know my thoughts concerning the secrets which I possess. And you spurned [my counsel](Prov: 1:25) … Then they will call upon me [but I will not answer (Prov. 1:28). This is why [the passage] states, “This concerns one who removes Kabbalah and wisdom. [Kabbalah] means the written Torah, [which symbolizes] Tiferet, and [wisdom] refers to the oral Torah, which is Malkhut. This is the mystery of the vav heh in which the yod heh is concealed,³⁴Cf. n. 18 above. as it is written, The hidden things are for the Lord our God. There the secret of God is revealed—to us and our children forever (Deut. 29:28).

He [Rabbi Aba] answered: all of Torah secret and revealed, and the God's Holy Name is secret and revealed, and it is written "the secrets are for Ad-nai our God and the revealed for us and our children" (Deut. 29:28). "The revealed" is what we have permission to ask, to delve into and to see, and to know. But "the secrets" are God's and who [among humans] is able to know and cling one's mind to what is closed, and all the more so to ask?!

²¹ Above these "limbs" is the "head" in which chochma (wisdom) is the²² right brain, the seat of thought, and bina (understanding) is²² the left brain and the heart, the heart's ability to discern. Concerning these, it is written, "The hidden things belong to G‑d ²³ corresponding to chochma our G‑d²⁴ corresponding to bina". (Deut. 29:28). Keter Elyon (Supernal Crown) is the keter of malchut, concerning which it is said, "I²⁵ G-d declare the end from the beginning". (Isaiah 46:10).²⁶ Keter surrounds and contains the two hemispheres of the brain, chochma and bina, like the leather box of the Tefillin²⁷ that surrounds and contains the parchments . Within²⁷ this unified system of "limbs" and "head" which constitute one "body" or "tree," is the Divine Name "spelled-out" with alefs, i.e. Mah, thus: Yud-vav-dalet = 20, hei-alef = 6, vav-alef-vav= 13, hei-alef= 6.²⁸ With this name You determine the way²⁹ in which Your Light is transmitted through the sefirot of Atzilut. This name therefore fills and saturates³⁰ the "roots" and the "trunk" of the "tree" of the sefirot, together with its "limbs" and "branches", as water irrigates and saturates a tree. It³¹ the "tree" then grows in proportion to how much "water" flows through it.
