Theia Philosophia: A Manual of the Royal Arte

This work is a unique testament to a spiritual path and discipline – a ‘theurgia’ or ‘god work’ – crafted from the world’s ageless spiritual traditions. Rendered in prose more redolent, at times, of sacred texts, the author’s writing style facilitates introspection and a re-consideration of our own spiritual path within the larger framework provided by the notion of a Prisca Theologia.

Theia Philosophia: A Manual of the Royal Arte by Jason Arthur Green is a manual of theurgy: the sacred work by which the soul seeks union with the divine. At its heart stands the pursuit of Henosis, the unification of the mortal and immortal, approached through disciplined practice, contemplative refinement, and the awakening of the soul to its highest possibilities.

Rather than presenting theurgy as a fixed dogma, Green offers a living framework for spiritual ascent. The work draws upon Hermetic, Platonic, Kabbalistic, Vedantic, and perennial streams of wisdom, bringing them into conversation as expressions of Sophia Perennis, the timeless wisdom underlying the world’s sacred traditions.
The result is both practical and visionary. Theia Philosophia equips metaphysicians, theurgists, and esoteric practitioners with principles, tools, and contemplative orientations that may enrich existing traditions or inspire the creation of a personal theurgic paradigm. Its aim is not merely the study of divine things, but participation in them: a path of sacred philosophy enacted through practice, devotion, and inner transformation.

Composed over nearly a decade of research, experimentation, and dedicated spiritual work, this monograph bears the mark of lived experience. Its prose often approaches the tone of a sacred text, inviting introspection while leading the reader toward a renewed understanding of philosophy as Fons Vitae — a fountain of life from which theophany, gnosis, and spiritual illumination may arise.

Jason Arthur Green is a South African philosophos, hieratic poet, and theurgist whose work is shaped by ancient philosophy, comparative religion, esotericism, apophaticism, noetic gnosis, and the perennial streams of wisdom.
Theia Philosophia is intended for readers who wish to deepen their spiritual practice through theurgy, sacred philosophy, ritual discipline, and contemplative work.
