Moshe Chaim Luzzatto discusses the doctrine of "Adam Kadom" within Jewish mysticism.
Kalach Pitchei Chokhmah 60, Sefaria, accessed February 15, 2022
BaN and MaH were bound up under Malchut and Yesod of Adam Kadmon, and then coupled together to bring about the repair.
After the emergence of the lights of the Eyes of Adam Kadmon – these being BaN – they were bound under the rule of Malchut of Adam Kadmon. And when the radiation of the Forehead – MaH – emerged, it was bound under the rule of Yesod of Adam Kadmon. Yesod and Malchut of Adam Kadmon then coupled together, and thus the stern judgments were sweetened and the government operated in a mode of repair and love.
. . .
Part 1: After the emergence of the lights of the Eyes of Adam Kadmon – these being BaN – they were bound under the rule of Malchut of Adam Kadmon. For the nature of the lights is such that, besides the original sources from which they emerged, we must also take into account the sources to which they are bound and from which they take their power and rule in the governmental order. In accordance with this principle, these lights emerged from the Eyes and were afterwards bound to Malchut of Adam Kadmon and received their governmental power from there.
And when the radiation of the Forehead – MaH – emerged, it was bound under the rule of Yesod of Adam Kadmon. In other words, since the purpose of this radiation was to repair the first lights, it was bound up under Yesod, which is the power that repairs Malchut.
Part 2: Yesod and Malchut of Adam Kadmon then coupled together... After these lights emerged from the Eyes and Forehead and had been bound under Yesod and Malchut, Yesod and Malchut of Adam Kadmon then coupled for the sake of the lights bound up with them. ...and thus the stern judgments were sweetened... This coupling caused a sweetening of strict judgements throughout the entire governmental order.
