The core of the gate is אֵם, 'em, mother. Aleph-Mem, is like Gate 1, Aleph-Beit, Ab, Father, ox-house, strength of the house. 'em, Mother, ox-womb, is strength of the womb. The point of departure or division is the lips parting to reveal the womb, strength of the womb shown in childbirth. Mother. Or, looking differently, Aleph is separation, and Mem the womb, bringing the idea of the point of departure or division. A people or tribe or nation, leom and 'ummah, is the fruit of the womb and the mother, those that come from her. The use of Aleph-Mem as metaphorical mother, the mother of a thing, is important. We see this in the vocal words, na'am and neum, prophecy and utterance. Speech is the beginning, the mother, of action. "God said...and it was so." In 'aman, we find meanings of nourishment, commonly seen as part of what it is to be a mother. A craftsman, 'aman, can be seen as the mother of his or her art. In 'amen, so be it, we see the commitment to something, and that commitment is the mother of it. Reversed, the core is מָא, ma', though this is the Aramaic form. Ma' is questions and exclamations. This links well with mother, for questions are the mother of discovery, and exclamations bring forth. In a way, ma'en/me'en, to refuse, refusing, unwilling to obey, are the opposite of their anagram, na'am/neum, prophecy, and the opposite of the point of departure/division of 'em. But this isn't quite true. Refusal and unwillingness to obey is it's own departure and division from the authority that is refused, and this act is the mother of what comes of it. Ma'n, vessel or utensil, relates well make to the womb, for the womb is a vessel. Mystically, Nun is a servant or vessel of the divine. Ma'n can be seen as "Who is the vessel of the divine?" The vessel of the divine is filled with the divine in the same way the womb is filled with the unborn baby. Or ma'n with the anagramic meaning, 'em, could be the mother of the vessel, or the vessel that is of the mother, the womb. Shamma', desert, is a bit harder. Shin is the tooth, and symbolically, this is nourishment. But desert? The desert by definition isn't nourishing. But Shin as a prefix changes a verb into the doer, so Shin-Mem-Aleph, Shamma', would be One Who Mem-Alephs. One Who Questions? That Which Questions? Does this imply the desert is that which brings questions? I'm not sure. It is interesting that the word is made from the Three Mothers, from Shin, Fire, Mem, Water, and Aleph, Air. Me'ah/ma'ah, hundred/hundredth, is problematic as well.
Aleph (1) + Mem (40) = 41. Or, with the final Mem, Mem is 600, so 601. In addition to 'em, 41 is fecundity, ram, force, hart, My God, to fail or cease, Divine Majesty, terminus, to burn, terror, to go round in a circle. 601 isn't anything by 'em. 41 reduces to 5, Heh, and 601 reduces to 7, Zayin. Heh is the window, and mystically the first breath. Zayin is a weapon, and mystically marriage. 5 is also mist, vapour, back, food, elevation, top, pit, water-hole. 7 is also lost, ruined, desire, good fortune, was weary, riches, power, fish. Fecundity fits well, productiveness in offspring, vegetation, intellectual pursuits, basically to be good at giving birth. The others are harder. The destructive and ending words from 41 seem to be the opposite of birth and motherhood. Same with many from 7. But marriage fits well. And a water-hole could easily be seen as a womb.
The 12th Gate is definitely the Gate of the Mother. It is akin to the 1st Gate, the Gate of the Father, but a different type of strength. The 1st Gate is about protecting, the 12th about nourishing. While not every male is a protector and not every female is a nourisher (and in fact the reverse can be true), the role of the Father is as protector and the role of the Mother is as nourisher. The Gate of the Mother is the Gate of Nourishment. The lesson to learn, to cross the gate, is how to nourish those things we create, those things we give birth to, in our lives.
