Subterranean Worlds of Inner Earth
The idea that our planet consists of a hollow, or honeycombed, interior is not new. Some of the oldest cultures speak of civilizations inside of vast cavern-cities, within the bowels of the earth. According to certain Buddhist and Hindu traditions, secret tunnels connect Tibet with a subterranean paradise, and they call this legendary underworld Agartha. In India, this underground oasis is best known by its Sanskrit name, Shambhala, thought to mean 'place of tranquility.' Mythologies throughout the world, from South America to the Arctic, describe numerous entrances to these fabled inner kingdoms. Many occult organizations, esoteric authors, and secret societies concur with these myths and legends of subterranean inhabitants, who are the remnants of antediluvian civilizations, which sought refuge in hollow caverns inside the earth.
