“…the first Heaven is the atmosphere, the second, cosmic space, and the third Heaven is the invisible world.  It was into the invisible world that the Apostle Paul was caught up, and where he contemplated God.  He also was caught up into Paradise, which, as the highest part of the world, is divided from it by a  revolving, flaming sword.”
(Martyr Daniel Sysoyev ‘Instructions to Immortals’)
