...and then everything will be complete. In other words, to complete the desired labor in its entirety requires all of this: that the Tzimtzum should carry out everything in its power, and not only this, but that at the end of everything produced by the Tzimtzum, the light of Eyn Sof, blessed be He, should shine, as explained above.
Part 2: Accordingly, at first the light was not joined with the vessels... In other words, what actually happened was that the light became hidden above. For although it entered, it was unable to join with it but went back and became hidden, as it goes on to say:...but became hidden above... This is like the way the soul stands above in the Garden of Eden all the time that the body is being purified in the earth, bringing out the evil from it. Even from above, the soul radiates what it must to the body during this time (i.e. הבלא דגרמי, hevla degarmei, the “vapor of the bones”). And so it is with these vessels, as will be discussed below (see Opening 54).
