There are many false secret societies and deceptions along the path of truth. It is up to the initiate to have the mental fortitude to make logical and reasonable decisions when evaluating such schools or teachers.
33rd Degree Freemason, Manly P. Hall had said this about false schools:
"Ceremonial magic is the ancient art of invoking and controlling spirits by a scientific application of certain formulæ.
A magician, enveloped in sanctified vestments and carrying a wand inscribed with hieroglyphic figures, could by the power vested in certain words and symbols control the invisible inhabitants of the elements and of the astral world.
While the elaborate ceremonial magic of antiquity was not necessarily evil, there arose from its perversion several false schools of sorcery, or black magic." - Manly P. Hall
