Hollow Earth Theory suggests that Earth is entirely hollow, or otherwise contains a substantial interior space, which some believe to be inhabited by other beings. Agartha (sometimes referred to as Agartta, Agharti, Agarta or Agarttha) is the name of this legendary city-space that resides within the earth’s core.
Frequently associated/confused with Shambhala, which figures prominently in Vajrayana Buddhism and Tibetan Kalachakra teachings and revived in the West by Blavatsky and the Theosophical Society. Theosophists in particular regard Agarthi as a vast complex of caves underneath Tibet inhabited by evil demons called asuras. Helena and Nicholas Roerich, whose teachings closely parallel Theosophy, see Shambhala’s existence as both spiritual and physical.
