The northern regions were thought to be a land of everlasting life or renewal of life where special beings might be found. In the ancient epochs of the earth there were beings who dwelt in the polar regions who had poorly developed physical bodies but highly developed ether bodies with great clairvoyant faculties.
They could understand the wisdom of the stars and the hierarchies of spiritual beings; they belonged to a “group soul” of an advanced nature. They can be thought of as living in the air in a kind of paradise and were not dependent on the earth.
They were to develop over time into the more advanced human beings of Atlantis.
