BaN (gematria 52) and MaH (gematria 45) were bound up under Malchut and Yesod of Adam Kadmon, and then coupled together to bring about the repair.*
In AK, BaN was bound under Malchut; MaH was bound under Yesod (the drop of male waters). When they coupled, the repair began.
Op. 59 named the matkela — the joining of MaH and BaN. Op. 60 specifies where the joining begins. In Adam Kadmon, BaN was bound under Malchut of AK; MaH was bound under Yesod of AK. The Yesod-Malchut couple of AK is the cosmogonic seed of the matkela's operational form.
The drop of male waters terminology comes from the Lurianic tradition. Yesod, in the operational anatomy, is the source from which the seminal radiation descends; the Yesod-Malchut couple is the structural form of all later coupling. In AK, Yesod and Malchut couple, and MaH descends through Yesod into Malchut where BaN is bound — the cosmogonic seed of the matkela's operational mechanism.
This resolves an apparent contradiction in Lurianic literature. Etz Chayim Shaar Derushey Nekudot and Seder Atzilut describe the cosmogonic process in terms that appear to conflict; Klach's two-sources principle (BaN bound under Malchut; MaH bound under Yesod) shows that the two descriptions are two angles on one structure. The conflict dissolves when both sources are seen as operating simultaneously.
The operational consequence: the Yesod-Malchut couple of AK sweetens the stern judgments throughout the governmental order. The cosmic government runs in love-and-repair mode — operational, deed-relevant, sustaining the cycle's middle phase — because the matkela's operational form is set up at the AK level to make this possible.
Op. 96 names the chain radla → Mitkala → AK Yesod-Malchut → Atik Yomin → A"A → Atzilut — the full causal architecture in which Op. 60's Yesod-Malchut couple sits. Op. 64 will sharpen the MaH-Line / BaN-Residue identification. The closing chapters' Coupling-order doctrine (Op. 138) operationalises Op. 60's framework at the operational level.
