*The Treasure House of Images* (Liber DCCCCLXIII) is a Thelemic sacred text written by J.F.C. Fuller, structured as a series of ritualized meditations and adorations intended for ceremonial use within the magical tradition of Aleister Crowley's A∴A∴ and O.T.O. The work is organized into thematic chapters—Perception of God, Twelvefold Affirmation, and Twelvefold Renunciation—each containing twelve numbered invocations plus a unity, designed to be recited in correspondence with astrological and planetary rituals. Its core content is a sustained address to a transcendent, ineffable God-concept, with the practitioner oscillating between radical self-abasement (comparing themselves to a maggot, a blind man, a helpless infant) and ecstatic union with the divine. Distinctively, the text blends Kabbalistic cosmology (the progression from Nothingness through the Limitless Light to manifest creation) with densely sensory, often erotically charged imagery—sexual, violent, and natural—as vehicles for mystical annihilation of the self. The Renunciation chapters are particularly striking in their systematic surrender of all worldly attachments, from erotic pleasure and familial bonds to intellectual achievement, each given up in exchange for dissolution into divine rapture. A prospective reader should expect high ceremonial poetry in the tradition of the Psalms and the Song of Songs, but filtered through fin-de-siècle occult aesthetics and the specific theological framework of Thelema.
