To add another direction. What if the feeling the practitioner senses is actually similar to the feeling that Reiki and Healing practitioners feel under their hands as the 'aura' changes? I practice Reiki, and my hands feel hot to the client, but never to touch if I take my hands off and they feel them. I am kinesthetic and feel depths, textures, warms, around people, also areas of cold, hollow, flatness. many years ago studies showed that healers can tune their brain wavelengths into the wavelengths of their clients. Getting on the same wavelength is the same in NLP rapport terms, matching and mirroring the client. What if in CST the therapist was tapping in to the energy aura of the person as opposed to the actual flow of fluid?
