A person who does, or is doing, metaphysics is called a meta-physician.
"Metaphysical healing" means healing by means of remedies that are not physical.
The Cult I grew up in was called Christian Science, founded by Mary Baker Eddy
Whilst Christian Scientists may claim that the healing method employed by Mrs. Eddy was unique to her, any objective student will realize that there really is no essential difference between the methods taught and practiced by Quimby and his later followers and those adopted by Mrs. Eddy. The basis is exactly the same, i.e. firstly the removal of fear from the patient, which Quimby accomplished by quietly explaining the mental causes of their malady to them, and then the replacing of this fear with faith, conviction, and firm expectation that they are healed. As it was exceedingly difficult for some of his patients to believe that healing could be affected in this way, he would often manipulate the patient's head in order for them to see that something had been done. In his manuscripts it becomes clear that he claimed no healing efficacy in this manipulating of the head, other than to help with the patient's faith. Quimby's conviction was that it is faith and expectation that invokes the Divine healing power, and whether one calls this power omnipresent Wisdom as Dr. Quimby did, or Divine Mind as Mrs. Eddy did, or Universal Mind as many New Thoughters do, or God as most others do, makes no real difference. Jesus Himself said as much with His statement "Thy faith hath made thee whole."
I had grown out of my Christian Cult, when my mid-life transition wife gifted me with Louise Hay's primer on meta-physical healing. Where Mary Baker Eddy and Quimby were using a broad spectrum mental-antibiotic Hay listed a targeted mental cause and affirmation cure for nearly every malady known to man.
When Hillary was falling into her SUV and the TV witch doctors were suggesting she had Parkinson's, Hypothyroidism etc, I thought this Hayism fit:
Thyroid: Humiliation. “I never get to do what I want. When is it going to be my turn?”
“I move beyond old limitations and now allow myself to express freely and creatively.”
I had a new home buyer prospect that visited me at least once a month without buying. She had 'buck' teeth, so I opened my Heal Your Body book to teeth:
Teeth: Represent decisions. Long-standing indecisiveness. Inability to break down ideas for analysis and decisions.
“I make my decisions based on the principles of truth, and I rest securely knowing that only right action is taking place in my life.”
I did the affirmation for her and the next time she showed up I wouldn't let her leave my office without a $500 earnest money check. Here is an A-Z listing.
The study of meta-physics has led to the "Law of Attraction" and the power of mental vibration energy. The study of the Occult - Astrological Psychology shows us as individuals where we need to send those good vibrations.
