Etheric healing comes from Source. The Source of life is your own construct. Source may be coincidence, or a random conglomeration of the laws of physics. It may be a personal god or a guide, or a psychological model. The issue in healing is not whether there is a Source, but how you and your clients relate to it.
Life exists, so it comes from somewhere.
This technique is about how to link back to Source through the higher etheric pattern to reflect the original life intention. Whatever a patient's belief of Source may be, if they are not relating to it through their etheric patterns, they will be experiencing displacement of energy, which is the cause of ill health. There are many times in a day that we hand back to Source the responsibility for critical life events. For example, there is a natural organic rhythm in our own bodies that we do not consciously control, except indirectly through sensible living. In the final analysis, we do not co-ordinate our own hormonal secretions, our heartbeat, our rates of oxygen absorption, our brain chemistry, and so on.
