The Emanating Sephiroth from Cornelius Coburn's blog

(more passages from the vaults of antiquity)

Mechanically, the propagating aether lays down a medium/context, i.e. an expanding four dimensional construct in which the sephiroth undergo their development. Much in the same way an artist prepares a canvas followed by a work of art. The former is nearly instantaneous while the Latter is a building up anabolic process that is measured in eons.

 
Each sephirah, or period of cosmic development has a peculiarity, uniqueness, or quality that distinguishes it from the others so it is given a special name, and in this case there are ten particular phases of cosmic evolution, plus Da'ath makes it eleven.

As of late I prefer refer to these (concentric) spheres according to their number or simply, 'emanations' as the traditional naming of 'some' tend to make me cringe.
