What Would Need to Be True
That somatic trauma theory actually does use "vital force" or equivalent language, rather than purely mechanical nervous-system language — the structural parallel may be more visible in the phenomenological literature than in the clinical literature
That the Aztec extraction model is as systematically described as Maffie's reconstruction suggests — specifically that tonalli (the vital force lodged in the head) and teyolia (the vital force of the heart) are what sacrifice specifically targets
A third case study somewhere on the spectrum — the ritual scarification or blood-letting practices in non-lethal sacrifice traditions, where the body is wounded but survives, would be the natural test case
