I Make Myself Invisible in Articles by Aleister Crowley.

“A girl played the violin during the rites. She was a good violinist, but under the influence of the ceremonies, she was more; she played sublimely, like a supreme virtuoso, in the magical invocations directed upon her.” [via, also], [see], [see]

  1. “I accordingly condensed and published knowledge in a periodical called The Equinox. Headquarters at this time was a studio in Victoria Street. There in our spare time we began to celebrate the rites of Eleusis.”
  2. Stoker, Huysmans, and Pessoa on an imaginary journey together
  3. “The ‘Black Mass’ is a totally different matter. I could not celebrate it if I wanted to, for I am not a consecrated priest of the Christian Church. The celebrant must be a priest, for the whole idea of the practice is to profane the Sacrament of the Eucharist. Therefore you must believe in the truth of the cult and the efficacy of its ritual.”
  4. “During one ceremony in July 1909, in the Victoria Street studio, we invoked Bartzabel, the spirit of Mars. One of those present was a man of importance in the Admiralty, a commander whose name is too well known to mention. He asked the spirit, which had been invoked in a specially purified and consecrated man, if ‘nation would ever rise against nation.’ Bartzabel answered that it would. Questioned further, the spirit said that war would break out within five years, and that the nations which would be smashed would be Turkey and Germany. Within a fortnight of the end of those five years the Great War broke out.”
  5. “I then went to Egypt, and–to my intense surprise–was summoned by the secret chiefs of the Order. I was commanded to return to England, there to reconstruct the system of organisation, as the outer form of the Order had broken up through the fall of its chief ambassador to the world ‘without the Veil,’ and to put the secrets in writing.”
