The lights execute their functions through the holy names which make up the Torah.
The whole Torah is the Names of the Holy One, blessed be He. Torah is both the master plan of creation and its master implement.
Op. 23 closes the Letters and Names unit with one of Klach's most expansive claims. The holy Names of God are specific letter-combinations that execute specific cosmic functions. And the whole Torah — every letter of it — is composed of these Names. The Torah is therefore both the master plan of creation (the why) and the master implement by which creation is enacted (the how).
The rabbinic tradition that the whole Torah is composed of Names of the Holy One has its strongest formulation in the Zohar (Yitro 87a) and in Ramban's introduction to his Torah commentary. Klach deploys it as a structural claim. Every Name is a specific letter-combination with a specific cosmic effect; every word in the Torah is composed of Names; therefore the Torah is operationally a system of cosmic actions, not just a record of historical events or a code of laws.
This has two simultaneous aspects. Esoteric meaning: the Torah is the blueprint of creation, the why — the cosmic reasons embedded in the verses' deepest readings. Letter-permutations: the Torah is the executive tool of actual creation, the craftsman's instrument. Both readings are correct. Bezalel built the Tabernacle by combining letters, the rabbinic tradition holds; the same combinatorial logic runs through every word of Torah.
Names operate through three channels. Speech: liturgical recitation and prayer activate the Names through articulation. Writing: amulets (kameot) carry written Names as protective or operative instruments. Meditation (yichudim): contemplative concentration on Names performs cosmic-spiritual work without external sound or sign. All three are recognised channels of the Names' operation.
The Names doctrine returns operationally throughout the book. Op. 31 (Adam Kadmon = the Tree of the Four-Letter Name; the Name's four letters map to the five Partzufim and four expansions). Op. 55 (AV (gematria 72) is Arich Anpin) operates on the four-expansion arithmetic Op. 22 introduced and Op. 23 names as the Torah's executive instrument. The closing chapters of the book continue to operate on the Names framework Op. 23 establishes here.
