It thus turns out that there are two upper aspects that are fit for fusion through collision in the partition: (a) the opacity of the third level,216This is the level with the greatest opacity remaining in the partition after the erosion of the surrounding light in this particular example. which blocks the supernal light and receives the fusion through collision upon which the level of Ḥokhma emerges,217This is the new partzuf generated in this example as a result of the third level of opacity generating returning light of the height of the level of Ḥokhma. and (b) the aspect of enclothing of the fourth level.218This is the remnant of the fourth level of opacity of the partition that was not lost, the “trace of enclothing.”
Although the aspect of enclothing is unfit for a fusion through collision, since it does not contain opacity that blocks the spread of light, nevertheless, when it is incorporated and participates in the opacity of the third level, a fusion through collision occurs upon it as well, and a height near to that of Keter219Returning light that is the height of Keter is generated by opacity of the fourth level in a partition.
Since the aspect of enclothing here is a remnant of the fourth level, the height of light generated by it in this second-hand fusion through collision is also that of Keter. is generated from it.
