"According to certain esoteric systems and spiritual traditions, Hyperborea was the terrestrial and celestial beginning of civilisation. The home of original Man. Some theories postulate Hyperborea was the original Garden of Eden, the point where the earthly and heavenly planes meet. And it is said Man transgressed Divine Law in this Golden Age civilisation, the ultimate price being his banishment to the outside world. Man ventured into other regions of Earth, establishing new civilisations, bringing to an end this great and glorious Golden Age."

"Hyperborea was a floating island in the North Pole sky. A suspended continent with thousands of people in several cities among forests, orchards, fields, mountains and rivers."

"Now perhaps he will be deceived as with the tree of knowledge and will come to the tree of life and eat from it and become immortal and rule and condemn us and regard us and all our glory as folly. And then he will pass judgment on us and the world. Come, let’s cast him out of paradise down to the earth, the place from where he was taken, so that he will no longer be able to know anything better than we can.” And so they cast Adam and his wife out of paradise."
