Trauma is a word that gets used to mean too many things. In the BCST tradition we use it narrowly: trauma is what happens when an event arrives faster than the system can absorb it, and a piece of the experience is held in the tissue rather than processed through.
That holding is not a flaw. It’s a survival adaptation. The body, faced with too much, brackets off the part it can’t metabolize and gets you to the other side. The cost is that the bracketed piece doesn’t go away. It waits.
The autonomic nervous system
The autonomic nervous system has two main branches: the sympathetic (mobilizing — fight, flight, push through) and the parasympathetic (calming — rest, digest, repair). A healthy system swings between the two with a smooth rhythm.
After a trauma, the swing breaks. The system gets stuck in sympathetic activation, or in a deep parasympathetic shut-down, or oscillates between them at high amplitude. None of those are bad. They are descriptions of a system that has not yet had the conditions to come back into rhythm.
What BCST offers
A craniosacral session is, at its simplest, a long, quiet input into the autonomic nervous system. The light touch is non-mobilizing. The slow rhythm gives the system something steady to come into resonance with. Over weeks of sessions, the bracketed piece often comes forward — not as a memory you have to relive, but as a sensation that finally finds its way out.
The other half of trauma work is verbal. A practitioner trained in verbal skills (a tradition I trained in with Anna Chitty) can track the autonomic state through conversation and gently steer the dialogue away from re-traumatization and toward integration.
A note about pace
Trauma work cannot be rushed. The body has a pace. Our job is to meet it, not to push it. If you’ve been told that your trauma is taking too long, that’s usually the wrong frame. The right frame is whether the conditions for healing are in place. They usually aren’t, and that can be fixed.
