But if you penetrate from everything changing to the ultimate, then we have the rock of eternity and we have the truth which only can rest on this rock. Now this fundamental reality is represented in degrees called “hierarchies.” The line from above to below is the line of emanation. The line from below to above is the line of salvation. The hierarchies represent both ways. They are the way in which the Divine abyss emanates. They are, at the same time, the revelations of the Divine abyss, as far as it can be revealed, in the way upwards – in the saving union with God.
