What do you know about Agartha?

Question

Is there a civilization living underground (beneath earth's surface) somewhere at the north pole? It is said that they are more advanced than us, are rather tall, and built their own "sun". They also have well organized cities, complete with vegetation and some wildlife.

Answer 1

Agartha (sometimes Agartta, Agharti or Agarttha) is a legendary city that is said to reside in the Earth's core. It is related to the Hollow Earth theory. It is a popular subject in Esotericism.

Agartha is one of the most common names cited for the society of underground dwellers. Shamballa (also known as Shambalah) is sometimes said to be its capital city [1]. The mythical paradise of Shamballa is known under many different names: It has been called the Forbidden Land, the Land of White Waters, the Land of Radiant Spirits, the Land of Living Fire, the Land of the Living Gods and the Land of Wonders. Hindus have known it as Aryavartha, the land from which the Vedas come; the Chinese as Hsi Tien, the Western Paradise of Hsi Wang Mu, the Royal Mother of the West; the Russian Old Believers, a nineteenth-century Christian sect, knew it as Belovodye and the Kirghiz people as Janaidar. But throughout Asia it is best known by its Sanskrit name, Shambhala, meaning 'the place of peace, of tranquillity.'

While once a popular concept, in the last century little serious attention has been paid to these conjectures (with the possibly apocryphal exception of Adolf Hitler), and the theory is not supported by modern science. The idea of subterranean worlds may have been inspired by ancient religious beliefs in Hades, Sheol, and Hell. Ferdynand Antoni Ossendowski's 1920 book Beasts, Men, and Gods also discusses Agartha.
