Nineteenth-century French occultist Alexandre Saint-Yves d’Alveydre published the first “reliable” account of Agartha in Europe.[4] According to him, the secret world of “Agartha” and all of its wisdom and wealth “will be accessible for all mankind, when Christianity lives up to the commandments which were once drafted by Moses and God”, meaning “When the Anarchy which exists in our world is replaced by the Synarchy.” Saint-Yves gives a lively description of “Agartha” in this book as if it were a place which really exists, situated in the Himalayas in Tibet. Saint-Yves’ version of the history of “Agartha” is based upon “revealed” information, meaning received by Saint-Yves himself through “attunement”.
