After the upheavals and repressions of the second world war, Spiesberger headed an esoteric study circle, where he met his future wife, Christa.
Under high usage (hohem Einsatz), he wrote the lodge newspaper "Leaves for applied occult art of living" ("Blätter für angewandte okkulte Lebenskunst"), as well as 42 books as a special titled "Inauguration" ("Einweihung").
Gregory gave Eratus [words seem to be missing here] on 18 March 1957 which made eternal faithfulness unto gradus solos (master level), at the initiation of the lodge and the demiurge Saturn.
Due to his knowledge and diligence, he expected to assume leadership of the lodge after the demise of Gregorius'; the married Gardner, however, put forward his long-term lover, Sorella Roxane for the Office of the Grand Master.
Due to divergent views on spiritual issues Spiesberger left the lodge, but continued to devote his time to lectures and his literary activities.
Spiesberger is well known as the single most important person to revive Germanic mysticism after the second world war, including the Armanen Runes and the Pendulum.
What Spiesberger essentially tried to do was remove the "racist" aspects[5] of the Armanic and Marbyan rune work and place the whole system in a pansophical, or eclectic, context.
To Guido von List, Friedrich Bernhard Marby, Siegfried Adolf Kummer and Rudolf John Gorsleben, the runes represent the key to esoteric understanding.
