Holy Guardian Angel
Crowley often wrote that every adept's path will be unique. He also wrote that two major milestones are fundamental to Thelemic mysticism, which he called the knowledge of and conversation with one's Holy Guardian Angel and the crossing of the Abyss. Crowley wrote, "the two crises—the Angel and the Abyss—are necessary features in every career. The other tasks are not always accomplished in [any given order]".
