‘There is nothing, absolutely nothing, to object to in what Guénon wrote. It is irrefutable.’
André Gide, as quoted by Mark Sedgwick in Against the Modern World: Traditionalism and the Secret Intellectual History of the Twentieth Century.
‘Agartha, it is said, was not always underground and will not always remain there. A time will come, according to the writings of M. Ossendowski, when those who live in the communities of Agartha will leave their caverns and return to the surface. Once, before their disappearance from the visible world, they had another name but after their departure they took the name Agartha, meaning “unreachable” or “inaccessible”, “inviolable”, because they found it convenient to establish their habitation of peace, according to M. Ossendowski, underground more than six thousand years ago. As it happens this dating corresponds to the beginning of the Kali-Yuga, or “Dark Time” (the Iron Age) of western culture. Kali-Yuga is the last of four periods in which the Manvantara are seen. Their reappearance will be in harmony with the general purpose of the age.’
René Guénon, Agartha.
