BPM III — psoas struggle (left)
Birth-canal propulsion
This point is an editorial marker for the left psoas and lower-abdominal cluster often used in somatic descriptions of BPM III's intense pushing, resistance, and birth-canal struggle. Grof's matrix is experiential; this coordinate does not establish that the psoas is the biological cause of such sensations.
