"No academic intending to research the modern esoteric currents can
renounce Koenig's works. Nowhere else, can such a fullness of original
documents, letters, charters, patents and rituals plus unknown
photographies regarding OTO and pertinent organisations be found ...
The dictum remains: Koenig's works are a must for all who deal with
the esoteric groups of the last 100 years." [In: Under Cover 1995; Aries 20/97]
