We do not ordinarily think of learning a new unconscious mentality, perhaps a whole new relationship between our cerebral hemispheres, as we think of learning to ride a bicycle. Since this is the learning of a now difficult neurological state, so different from ordinary life, it is not surprising that the cues of the induction had to be wildly distinctive and have an extreme difference from ordinary life. And they certainly were different: anything odd, anything strange: bathing in smoke or sacred water, dressing in enchanted chitons with magical girdles, wearing weird garlands or mysterious symbols, standing in a charmed magic circle as medieval magicians did, or upon charakteres as Faust did to hallucinate Mephistopheles, or smearing the eyes with strychnine to procure visions as was done in Egypt, or washing in brimstone (sulphur) and seawater, a very old method which began in Greece, as Porphyry said in the second century A.D., to prepare the anima sfiritalis for the reception of a higher being. All these of course did nothing except as they were believed to do something — just as we in this latter age have no 'free wil' unless we believe we have.
