Line of pull is the direction a shortened tissue drags a segment, which the practitioner traces before releasing it.
A forward head may be the end of a line that starts in the chest or the hip; a rotated pelvis may be the end of a line that starts in the foot. In 📝Postural / Structural Realignment the hands follow that drag through 📝Fascia and muscle rather than chasing the sore spot alone. The line is a working picture, not a dissected meridian and not a diagnosis.
Clients feel it as "you are not where it hurts." Naming the line makes the session honest about source and compensation. Work stays at the barrier along that line; forcing past it produces guarding.
This is pattern language, not a claim that a structure has been put back.
