ain soph aur

[solomon levi]

Ain Soph Aur is the Hebrew/Kabbalistic unmanifest preceding the Tree of Life
and its ten emanations/sephirot.

Its literal meaning is "boundless (infinite) light"
ain = nothing
ain soph = boundless; limitless
ain soph aur = boundless light

playing with some words we also get:

aur = gold
soph-aur = sulphur
soph-aur-ain = sovereign

sometimes it is written "en soph aur":

ens-offer/o-pher = bearer of the ens
en suffer = in suffering
