"The Bridge That Flows" is an illustration of these things: movement in the sacrum, forward and back; support for L4 and L5 from the pelvis, vertically to L4 on inhalation, horizontally to L5 on exhalation (support from the ilio-lumbar ligaments); the movement of the diaphragm in inhalation and exhalation, tied to L1, L2 and L3 and supported by L4 and L5; stretches in the sacrospinous, sacro-tuberal and sacro-iliac ligaments; activity generated by the stretch of ligaments in the psoas and sartorious muscles; movement of the temporal and parietal bones by the extensors, with changes in the cranial-sacral rhythm effected by nerve impulses generated through the movement of the parietal bones; and lastly, the ability to feel realized through activity spontaneously generated by the impact of consciousness on stretch.
