All these are called by their own individual names according to the way in which they spread and extend. The explanation of the spread of the Inner and Encompassing Light in the writings of the ARI relates only to Eyn Sof’s “looking down” over and providential supervision of the different levels in accordance with the laws of the Residue and its ordered levels.
In the vision this appears as lights made of perfectly wrought vessels, within and around which is the Light of Eyn Sof, blessed be He, on the levels of Inner and Encompassing Light.
