Aleister Crowley,
Liber III vel Jugorum
(1910)
“ On each occasion that thou art betrayed into thinking that thou art sworn to avoid, cut thyself sharply upon the wrist or forearm with a razor; even as thou shouldst beat a disobedient dog. Feareth not the Ox the Goad of the Ploughman?3. Thine arm then serveth thee both for a warning and for a record. Thou shalt write down thy daily progress in these practices, until thou art perfectly vigilant at all times over the least thought that ariseth in thy brain. ”
