"The Three Pillars are the Pillar of Severity, the Pillar of Mercy, and the Pillar of Mildness. The three Triangles are the Celestial Triangle, the Moral Triangle, and the Mundane Triangle. The Four Worlds are Ha-oh-lahm Atziloot, Ha-oh-lah B'ri-ya, Ha-oh-lahm Yetzirah, and Ha-oh-lamn Ahssiah. These are, respectively, the World of Emanations, Creation, Formation, and Action." (Donald Kraig, Modern Magick, Lesson Three, questions #2-4)
