To resolve this apparent contradiction, it must be understood that two things had to happen with respect to Zeir Anpin. The first is that Zeir Anpin had to be built on all his levels – i.e. as a structure of Ten Sefirot – through the process of sorting and purification (בירור, birur) from the World of Desolation, as explained in the preceding Opening. (The second thing that had to happen – the successive revelation of these already-built levels in the course of Pregnancy, Suckling and Maturity – will be addressed presently.)
