Now comes the spirit, incarnating. Yet another focus, which may be in sync with the body, at times, as in the desire to commune with another of the opposite sex when both are, as you say, horny. The spirit may also be in sync with the mind, at times, as when the desire to be of service to others melds with the opportunity to do research. But the body, mind, and spirit may all be pulling in different directions, and thus make the body sick. The faith healer discerns the misalignment and discusses this, nonverbally in most cases.
Counseling occurs, with suggestions on how better to proceed.
The faith healer convinces the parts of the afflicted to adjust to each other, so that the mind and spirit take each other and the body into consideration more effectively. Were this to be a verbal communication, there would not be so much mystery about faith healing, which can and does occur.
