discovering the True Will. Generally, magical practices in Thelema are designed to assist in finding and manifesting the True Will, although some include celebratory aspects as well. Crowley believed that after discovering the True Will, the magician must also remove any elements of himself that stand in the way of its success. Crowley was a prolific writer, integrating Eastern practices with Western magical practices from the Hermetic Order of the Golden Dawn. He recommended a number of these practices to his followers, including: basic yoga (asana and pranayama); rituals of his own devising or based on those of the Golden Dawn, such as the lesser ritual of the pentagram, for banishing and invocation; Liber Samekh, a ritual for the invocation of the Holy Guardian Angel; eucharistic rituals such as The Gnostic Mass and The Mass of the Phoenix; and Liber Resh, consisting of four daily adorations to the sun. He also discussed sex magick and sexual gnosis in various forms involving masturbation and sexual intercourse between heterosexual and homosexual partners; practices which are among his suggestions for those in the higher degrees of the Ordo Templi Orientis. One goal in the study of Thelema within the magical Order of the A∴A∴ is for the magician to obtain the knowledge and conversation of the Holy Guardian Angel: conscious communication with their own personal daimon, thus gaining knowledge of their True Will. The chief task for one who has achieved this goes by the name of "crossing the abyss"; completely relinquishing the ego. If the aspirant is unprepared, he will cling to the ego instead, becoming a Black Brother. According to Crowley, the Black Brother slowly disintegrates, while preying on others for his own self-aggrandisement. Crowley taught skeptical examination of all results obtained through meditation or magick, at least for the student. He tied this to the necessity of keeping a magical record or diary, that attempts to list all conditions of the event. Remarking on the similarity of statements made by spiritually advanced people of their experiences, he said that fifty years from his time they would have a scientific name based on "an understanding of the phenomenon" to replace such terms as "spiritual" or "supernatural". Crowley stated that his work and that of his followers used "the method of science; the aim of religion", and that the genuine powers of the magician could in some way be objectively tested. This
