For example, when the partition of the partzuf of Keter of Adam Kadmon was purified and ascended to the mouth of the head,213When a partition is purified of opacity, it then ascends to the head of its partzuf where it unites with the partition of the head. In that new context, remnants of its previous opacity are renewed (except the lowest level directly eroded by the surrounding light) and it is now able to undergo a new fusion through collision, creating a new partzuf. it was incorporated in the fusion there and its remnants were renewed.
From the perspective of the opacity of the partition, upon which the fusion through collision occurred, only the trace of opacity of the third level remained in the partition, since the last level, which is the fourth level, was lost.214These levels are specific to this example. In an example in which the partition had previously had the second level eroded directly, only the trace of opacity of the first level would have been renewed, while the second would have been lost.
However, the enclothing part of the fourth level still remained in the partition.215This is the key idea of this paragraph. Although the lowest level of the partition is eroded and lost because of the returning light, only one of two aspects of this level are fully lost. The traces, or remnants of opacity of the level are fully lost. There remains, however, a remnant of that level of the partition called “the traces of enclothing.”
This remnant, while unable to participate in a fusion through collision on its own, can join an existing fusion through collision with renewed opacity in the partition.
