Translation
No academic intending to research modern esoteric currents can do without Koenig’s works. Nowhere else can such a wealth of original documents, letters, charters, patents and rituals, along with unknown photographs concerning O.T.O. and related 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.
