聖守護天使
In most of his writings, Crowley described the Holy Guardian Angel as one's "Silent Self", at times equitable with one's deepest unconscious. In later writings, he insisted that the HGA is an entirely separate and objective being. Whichever position is taken, the object remains the same—to gain an intimate spiritual connection so that one's True Will can become fully known and manifested. When using the Tree of Life as a guide, this event occurs in the Sphere of Tiphareth.
