(0°=0): This grade exists primarily for the candidate to prove himself capable of executing the Great Work, and to prepare him for his initiation into the A.'.A.'. proper. His principal business is to begin such practices as he may prefer, and to write a careful record of the same for one year. In this, he is charged with the tasks of attaining a "scientific knowledge of the nature and powers of his own being". Crowley elsewhere mentions that the Probationer must demonstrate a reasonable level of proficiency in the core practices of the Order (as laid out in Liber E and Liber O). This is primarily to ensure that when advancement comes, the newly created Neophyte will have the necessary experience to guide his own Probationers in their work. Initiation into the following grade of Neophyte is conferred after at least one year, through an unpublished ritual titled Liber Throa.
