Unless talking therapy really includes ongoing attention to the body (and the deeper structures of the brain that are involved with body-wisdom), then real healing will come with glacial slowness if at all.
The wisdom and concerns of the reptilian brain cannot be ignored. It is preoccupied with our most basic survival needs. We cannot shut it off. In addition to ongoing moment by moment safety and security needs, it is also burdened with our history and operates based upon that history. If our history has certain patterns of threat and disequilibrium, it will continue to operate as though that is the nature of the world.
No matter how much insight we gain (higher cortical knowledge), we will not touch these deep patterns of self protection and self-maintenance (reptilian brain).
