Clearly each Sefirah must be part of the Residue, because the Residue is the totality of all that is destined to exist in the Sefirot wherever they are. The Residue consists of the totality of everything as a single whole. In this aspect the Residue is therefore called only the root of what was destined to come afterwards, but the truth is that it is the totality of all that is destined to be. Everything that came afterwards is all only the details of the Residue.
Every detail is part of the overall whole. If so, everything that exists in the Sefirot on every level is part of the Residue. Even though many different levels emerge later, this does not belie the fact that ultimately everything is rooted in and derives from the Residue. The various different levels could emerge only where we find them, but this is not a reason to say that they are not part of the supreme Residue, for as explained earlier, what was not initially included in the whole cannot exist afterwards as a detail.
