By Crowley & Neuburg

Crowley wore a black robe with a hood which enveloped his head but had eye-slits. He crouched in the triangle, to allow the demon to take possession of him. Some occultists have claimed that as a result of this rash act he was obsessed for the rest of his life. Neuburg remained in the circle. He called upon the archangels and their legions to protect him and chanted an incantation from the Grimoire of Honorius.

Crowley held a topaz and, looking into it, he saw the demon appear in the depths of the stone, crying the words which are supposed to open the Fates of Hell, Zazas, Zazas, Nasatanada, Zazas. The demon blustered, boasted and raged, speaking in Crowley's voice and also in his style - 'I have made every living thing my concubine, and none shall touch them, save only I... From me come leprosy and pox and plaque and cancer and cholera and the falling sickness.'

Neuburg thought he saw not Crowley but a beautiful woman in the triangle. She spoke softly to him and looked at him longingly, but he realised that she was really the demon, trying to entice him out of the circle. Suddenly there was a loud, wild laugh and Choronzon appeared visibly in the triangle. He heaped flattery on Neuburg's and asked permission to come and put his head under Neuburg's feet to adore and serve him. Neuburg recognised this as another ruse, an attempt to get into the circle, and refused. Choronzon, who was now in the shape of Crowley but naked, begged for water to quench his thirst. Neuburg again refused, commanding the demon to obey him by the Names of God and by the Pentagram. Choronzon was not in the least subdued by this and Neuburg, who was becoming increasingly frightened, threatened him with anger and pain and the torments of hell. But Choronzon answered magnificently, in the manner of Marlowe's Mephistopheles. "Thinkest thou, O fool, that there is any anger and any pain that I am not, or any hell but this my spirit?'

The demon broke into a torrent of furious and obscene blasphemies. Neuburg was frantically trying to write down all Choronzon's words and while his attention was distracted Choronzon craftily threw sand from the triangle on to the line of the circle, broke it and sprang into the circle. The unfortunate Neuburg was flung to the ground as the raging demon tried to tear out Neuburg's throat with his fangs. Neuburg desperately invoked the Names of God and stabbed at Choronzon with the magic knife.

The demon was overcome and writhed back into the triangle. Neuburg repaired the circle while the demon turned back into a beautiful woman and again attempted a seduction, but in vain. In the end Choronzon admitted defeat, but as the energy of the pigeons' blood was now exhausted he disappeared and the operation come to a close.

Crowley, who said that during all this he 'dwelt apart' in his robe and hood, noted that Choronzon appeared as a woman, as a wise man, as a wriggling snake and as Crowley himself. He had no fixed form, because he was the maker of form. He was 'the terror of darkness, and the blindness of night, and the deafness of the adder, and the tastelessness of stale and stagnant water, and the black fire of hatred, and the udders of the Cat of slime; not one thinf but many things'.
