Does he need to fall and rise again in order to develop more horns? Or can he do it just by experience and sacrifice?
Also, is heavenly hierarchy related to esoteric degrees? For example, does the fact that Sirius manage an entire galaxy mean his esoteric degree is high? Or are they not related at all, since hierarchy is related to the outer(planets, stars, galaxies; dust of the world) and esoteric degrees related to the inner plane of consciousness and inner development(wisdom, liberation, seeing into Truth, etc)?
