The first criterion is the partition that fuses with the supernal light through a fusion through collision, giving rise to the returning light and enclothing the supernal light. The height of the lower new partzuf will be commensurate with the measure of the enclothing of the supernal light (as explained in Petiḥa LeḤokhmat HaKabbala, section 21).170The height of the new partzuf is a function of the height of returning light that the partition releases, as that returning light enclothes the previous partzuf.
In this way, after the partition generated all the partzufim and the levels in the world of Nekudim, which did not endure but were broken and negated,171This refers to the breaking of the vessels of Nekudim, a complex process that is explained elsewhere. and the partition was purified172This purification takes place in the process that was explained previously, in section 63 above, through the beating of the surrounding light against the inner light. from all its five levels of opacity and returned to the head of Sag (as explained in Talmud Eser Sefirot, part 8, sections 2 and 4), all the levels that had emerged in Nekudim left their remnants in the partition.173This refers to remnants of opacity.
Therefore, when the partition was incorporated in the fusion in the head of Sag, those previous remnants were renewed within it.174The renewal of these remnants gives rise to new releases of returning light to create the partzufim of Atzilut.
