The mental body is a material organism that has its anatomy and occult ultraphysiology.
The mantra to cure diseases of the mental body is: S M HON.
S is pronounced with a whistling sound, acute, similar to that produced by compressed air brakes, like this: SSSSSSS.
M is pronounced as if imitating the mooing of an ox: MMMMMMMM.
The H is like a deep sigh. The syllable ON is pronounced extending the sound of O and N, like this: OOOOOOONNNNN.
This mantra is pronounced for one hour daily. The disciple should invoke daily the Archangel Raphael and Hermes Trismegistus, requesting the healing of the mental body. When diseases of the mental body crystallize in the physical brain, then madness occurs.
