For me, the secret entrance into the hidden world, where we can navigate, and interact with the Egregore, has been the dream world...
Only in the dream world did the clues come to life, like marionettes that pantomimed the flows of power in the waking world.
The endless corridors of the mafia king, where I encountered enslaved children, hooked to a glowing green fluid, monitored by hit men and spy women as they ran their deliveries came to me when I was in architecture school. The subtle idea that we evolve the world around us, as it revolves around us... and we evolve within it... To me when I saw movies like "Brazil" by Terry Gilliam, or read comics like "the Invisibles" by Grant Morrison, and when I contemplated the KalaChakra mandalas... I saw the proof that others detected this extension of reality.
It was apparent that we shared this perceptive ability. I learned to shift into this perceptive mode in various ways... Similar to the meditation methods of ancient gurus.. I learned to syncronize my breathing to the waves that moved the currents and energy of the city... I.E. traffic lights... I could breath in resonant loops to the 49 second red, 10 second yellow, 59 second green phases that the lights pumped out... And I could see the soul of the overseers...
This article "Secret World" by Crimethinc points out that the hidden world is being dived in and out of by perceptive people, willing to vibrate in dissonance to allow a vantage point that reveals the warp and woof of the tapestry we all inhabit... I recommend we all learn to perceive this world, and learn to manage it with a greater cogniscience, cultivating living healthy nests that are in balance with the environment.
