I believe that 'Healing Happens'. Which means that the body knows how to heal itself. As does everything else.
Healing is natural to this existence. When there is dis-ease, something has happened to dis-connect us, to send us in a different direction from wholeness. At our best we are one, and at our worst we have separated into warring factions. Healing makes whole once more.
It is possible to imagine how one could be lacking in communication skills with ones spouse or child. Problems would arise. Friction would become normal, Separation would grow, despite a wish on our part, on everyones part to come together . A third party, a councillor, pastor, therapist, friend could intervene and help the estranged parties to open lines of communication. Healing would ensue, and in fact, a deeper bond, a higher love, a more solid connection can evolve out of the ashes of the problem. Difficulty is an aspect of growth, an evolutionary agent. Both difficulty and healing are ongoing states. Neither is meant to be static.
The body is a living organism made up of many many parts. It cn also have breakdowns in communication that have to be healed. Rebalancing, through work on the fascial system, which is everywhere and which communicates between its parts, is what we work with to create the opportunity for healing to happen. Fascia connects, so when we work with it, we are also influencing everything else from organs that are encased in fascia, to muscle that can slide thanks to fascia, to bone and further. It is because of the connectivity of fascia that it is such a pivotal healing agent.
