292. Within the mystery of the Tabernacle are found high secrets of the Holy Name Adonai. The mystery of the Tabernacle resembles the supernal mystery of the Ark, as it is written, "Behold, the Ark of the Covenant of the Master (Heb. adon) of all the earth" (Yehoshua 3:11). "The Master of all the earth" is the holy secret of the name Adonai. It reflects the Holy Name Yud Hei Vav Hei, because THE LETTERS ADONAI are like the letters YUD HEI VAV HEI.
293. HE EXPLAINS: Aleph OF ADONAI is like Yud OF YUD HEI VAV HEI, WHICH IS ABA. The mystery of the Yud FULLY SPELLED is like Aleph, FOR IN THE SHAPE OF THE LETTER ALEPH THERE IS YUD ABOVE, VAV IN THE MIDDLE AND DALET BELOW, NAMELY YUD (YUD-VAV-DALET). This was established. Dalet OF ADONAI is the secret of Hei OF YUD HEI VAV HEI, WHICH IS IMA, BECAUSE WHEN MALCHUT SERVES AS A GARMENT TO THE LEFT COLUMN OF IMA, IT IS CALLED 'DALET'. The one resembles the other, all in one mystery and manner. IT WAS EXPLAINED THAT Nun OF ADONAI is the secret of the letter Vav OF YUD HEI VAV HEI, WHICH IS TIFERET, THE CENTRAL COLUMN. And though VAV is male, and NUN is female, they were combined within one another, TIFERET OF ADONAI, WHICH IS MALCHUT, THE SECRET OF NUN, IS INCLUDED WITHIN TIFERET OF YUD HEI VAV HEI, WHICH IS ZEIR ANPIN, THE SECRET OF VAV. It was explained that Nun and Vav are in the middle, combined together. NUN IS THE CENTER OF THE LETTERS NUMERICALLY COUNTED IN UNITS OF 'TENS', YUD (= 10), CAF (= 20), LAMED (= 30), MEM, NUN, SAMECH, AYIN, PEI, TZADI, AND VAV IS THE CENTER OF THE LETTERS NUMERICALLY COUNTED IN UNITS OF ONE: ALEPH (= 1), BET (= 2), GIMEL, DALET, HEI, VAV, ZAYIN, CHET, TET. Hei OF YUD HEI VAV HEI is the secret of Yud OF ADONAI, WHICH IS MALCHUT, since THE YUD in here is little Chochmah called 'the Wisdom of Solomon'.
294. The letters are comprised within one another, THE FOUR LETTERS OF ADONAI INCLUDED WITHIN THE FOUR LETTERS YUD HEI VAV HEI. They all belong to the same principle, including the one in the other, everything being one. Everything is one mystery by the holy letters. Therefore, the Tabernacle below on earth is based on the secret of the upper Tabernacle, WHICH IS MALCHUT CALLED 'ADONAI', and that upper Tabernacle is in the secret of yet another Tabernacle superior to all, WHICH IS BINAH. All are comprised within one another so as to form one whole. Hence it is written, "that the Tabernacle may be one" (Shemot 26:6).
