The initial trauma is fixed in the body at the deepest layers. Once the holding pattern is established, it is as though we are programmed to continue to injure ourselves in the same exact place in the same exact way. You can have a strong release of an emotional holding pattern in a superficial layer, and it might not have any effect on releasing the deeper roots of the pattern that are embedded into the bone. Only when you penetrate to the deepest layers can you free the deepest physical holding patterns and their causes. It is at the bone that these patterns can be freed.
Bone is harder, denser, more porous, and more contained than other tissue in the body.
It can absorb and hold more shock and trauma, too. It has the ability to store life experience, hold it in, and pull the tendons and muscles in toward it. What allows us to create and express ourselves out in the world is the tendons and muscles moving outward from the bone. The more trauma is held in the bones, the more the rest of the body is pulled into the bone. When bone is stimulated by touch, palpation, being leaned into or rolled on, it begins to awaken and change form.
