components, collected in one place, confined and directed by the Magician. The critical 
temperature corresponds to such magical conditions as quiet and inviolability; the cylinder to the 
constraint imposed by the Magician to prevent the dissipation of his invoked ideas. 
Such indeed is an outline of the theory of calling forth spirits to visible appearance (by "visible" we 
always intend audible --- too dangerously often tangible, and too unpleasantly often capable of 
producing impressions of the olfactory nerves). In practice, however, there is something lacking to 
success. 
Neuburg supplied the missing link, as I might have expedited from his personal resemblance to that 
Darwinian desideratum. There was some substance in him which was on the borderland between the 
manifest world of matter and the astral world of sensation. In his presence I found it quite easy to 
produce phenomenal phantasms of almost any idea, from gods to demons, which I happened to need 
at the moment. I had of course a very wide experience of so-called material manifestations; but for 
the most part these had been independent of my will and often contrary to it. I have already 
mentioned a number of such phenomena in connection with the Abramelin Operation. I had 
succeeded in suppressing them by preventing my magical force from leaking away. A miracle 
annoyed me as it annoys an electrician to find that his current is escaping, perhaps giving shocks to 
people who have strayed in its path. His first thought is to detect and correct the imperfection of 
his insulation. Years had passed without my magical energy breaking loose: I had persuaded it to 
work through the proper channels. 
Carelessness showed itself once more in Shanghai. I was invoking certain forces with Soror F. in her 
circle. After I had constrained them to come, I proceeded to make a circumambulation with the 
object of giving them the desired direction, and when I came to the west of the circle, I noticed 
that Soror F. had profanely left her slippers inside it. These, not being consecrated objects, had no 
business there; so I pushed them gently over the frontier with my foot. They were seized and flung 
furiously to the ceiling with such force that they broke off some of the plaster. There was no 
possibility that my foot had supplied the motive power, even had I kicked them away in a rage 
instead of pushing them as quietly as I could --- which I naturally did, to diminish the disturbance. 
There had been several other minor incidents of the same sort on subsequent occasions; but I took 
measures, as before, to suppress them. 
The manifestations which Neuburg helped to produce were of an entirely different character; they 
occurred in conformity with my will. I was able to

work more by sight and less by faith than I had ever done before. Even the use of the proper 
material bases for manifestation, such as the incense of Abra-Melin, Dittany of Crete, and blood, 
had rarely resulted in more than "half formed faces", partial and hesitating presentations of the 
desired phantom whose substance seemed to hover on the frontier of the worlds (rather like the 
Cheshire cat!). The clouds of incense used to grow denser in such wise as rather to suggest a shape 
than to show one. I could never be sure, even when my physical eyes told me that a form was 
present, whether my imagination and my desire were not playing tricks with my optical apparatus. 
Such shapes almost always vanished when I fixed my gaze upon them, and there was no means of 
saying whether this act, by releasing them from the constraint of my will, had enabled them to 
escape, or whether intelligent inspection had not simply dissipated an illusion. 
With Neuburg, on the contrary, there would be no doubt whatever as to the physical character of 
the beings which we evoked. On one occasion the god came to us in human form (we were working 
in a locked temple) and remained with us, perfectly perceptible to all our senses, for the best part 
of an hour, only vanishing when we were physically exhausted by the ecstasy of intimate contact 
with his divine person. We sank into a sort of sublime stupor; when we came to ourselves, he was 
gone. 
Again, at Victoria Street, a number of us were dancing round the altar with linked hands and faces 
turned outwards. The temple was dimly lighted and thick with incense. Somehow the circle broke
