My esoteric vision of the Hyperborea is the etheric North pole where there is always the right atmosphere - not too cold, not too hot - where the secret jewels of spiritual wisdom and the whole of planetary history are kept intact and recorded in scrolls that have no physical form. What they do there is make commentaries of planetary history. "Look, we sent Jesus and what did they do to him for their own peril!?" "Lets creates ideologies and philosophers of every sort and see what they'll Come up with." This is how these high initiates plan history. In every hundred years an initiate jumps from the high cliffs into the depths which is Human history. I think Blavatsky also wrote something along these lines (forgive me if I recall incorrectly); and our dear Nietzsche also had his idea of Hyperborea:
"Let us face ourselves. We are Hyperboreans; we know very well how far off we live. 'Neither by land nor by sea will you find the way to the Hyperboreans'—Pindar already knew this about us. Beyond the north, ice, and death—our life, our happiness. We have discovered happiness, we know the way, we have found the exit out of the labyrinth of thousands of years. Who else has found it? Modern man perhaps? 'I have got lost; I am everything that has got lost,' sighs modern man. This modernity was our sickness: lazy peace, cowardly compromise, the whole virtuous uncleanliness of the modern Yes and No. … Rather live in the ice than among modern virtues and other south winds! We were intrepid enough, we spared neither ourselves nor others; but for a long time we did not know where to turn with our intrepidity. We became gloomy, we were called fatalists. Our fatum—abundance, tension, the damming of strength. We thirsted for lightning and deeds and were most remote from the happiness of the weakling, 'resignation.' In our atmosphere was a thunderstorm; the nature we are became dark—for we saw no way. Formula for our happiness: a Yes, a No, a straight line, a goal."
