So, Mothers, Doubles, Elementals. 3, 7, 12. When the SY starts to talk about the Elementals, it does so through an illuminating recuperation of the Mothers and the Doubles, emphasizing in each case the way in which the Mothers and Doubles each manifest with an intermediary force.
The Mothers have a pan of liability (Shin) and a pan of merit (Mem), with the tongue of decree (Alef). The Doubles are three against three, with a mediator (I think the three-three-one pattern can manifest in a few ways, so let’s save that for another discussion). But the Elementals? They are at war (three lifegivers, three killers, three allies, three enemies).
