Hall opens by defining Theurgy as the “blessed magic” of the Hermetic Egyptians and the final rung on the philosophical ladder. Drawing on the Sepher Yetzirah, he explains that the six branches of philosophy correspond to the six directions of the cosmic temple—north, south, east, west, above, and below—while Theurgy is the immovable center, the tabernacle of the Ageless One. It is the “Unmoved Mover” of Philo, the samadhi or nirvana of the Orient, the silence after sound in Rosicrucian symbolism. All philosophical striving, he argues, ends not in more activity but in a transcendent suspension: a state of achieved power that no longer acts outwardly. Just as mastery of the physical world brings temporal superiority, mastery of the intellectual world brings spiritual sufficiency. Knowledge alone cannot satisfy; it depresses the average person unless transmuted by illumination. Theurgy is this transmutation—the “Wise Man’s Stone,” the pure spiritual gold extracted from the baser compounds of thought.

In the second half, Hall describes Theurgy as the inner fountain of wisdom that nourishes all parts of human nature. Philosophy must become a vibration within body, soul, and mind; consciousness circulates through its seven “mansions,” and the body itself is gradually purified. He illustrates this through the Taoist buffalo allegory: the black animal (material nature) is first restrained, then guided, then purified into white, then lifted to heaven, and finally dissolved into pure consciousness. The culmination of Theurgy is the disappearance of the self into absolute truth. Hall concludes with reflections on ancient initiates, the nature of divine wisdom, and contemporary scholarly discoveries, including the Denderah Zodiac and the Codex Sinaiticus. The Theurgist, he writes, is one whose quest has ended in achievement—one who possesses the unified faculty of reason, intuition, imagination, and inspiration, and who is therefore capable of understanding all natural mysteries.
