Part 1: The first order assumed by the emanated light... As we have already discussed, the Residue existed initially only as the first root of all that would be created afterwards, standing as a general whole waiting to divide into its particulars. Indeed, many powers are found there, and thus the ARI stated that this emanation contains worlds without end (see Etz Chayim, Derushey Igulim VeYosher 12:1).
To explain this further: The Tikkuney Zohar states, “There is no angel that does not have within it the name of HaVaYaH, blessed be He, and all the other names are considered attributes of this Name” (Tikkun 57 end). The Zohar states, “There are men who inherit three hundred and ten worlds, but it is impossible to ascribe any number to the worlds of the Master of the Universe” (Pinchas 257b). What this means is that although we usually speak only of four worlds, the truth is that there are worlds without number. This is because every complete governmental order consisting of an active source of influence (משפיע, mashpia) and a receiver (מקבל, mekabel) is called a “world” (עולם, olam), and is one complete system or “tree” of all the relevant sources of influence and receivers and their various orders and interconnections. There are very many such trees. Speaking generally, every name is a tree in itself, all of whose levels, influences and “chariots” (מרכבות, merkavot – governmental apparatus) are arranged in an order unique to itself.
