The Christ Letters
"ALL THE THOUGHTS taking form in your brain descend into your pituitary gland via your hypothalamus, and the negativity and emotional trauma (lowered vibrations) they contain is passed on to your organs, blood and entire body, causing a depletion in energy and eventual illness.
This is the phenomenon producing PSYCHOSOMATIC ailments acknowledged by the medical profession." [The Christ Letters, A14]
