When two or more names reach the same numerical total through different pathways, it is understood that this is a single essential root with which each one must be joined. Each follows its own pathway, but at the end of its winding and turning, that is where it reaches. And this is the mystery of the name of AV (72), which is contained in the four names of AV, SaG, MaH and BaN. For while each one has its own individual pathway, they all arrive at this.
This shows that it is one essential root which all of them must reach, each one in its own way. And the truth is that this comes from Arich Anpin, from which Abba and Imma, Zeir and Nukva emerge. Thus Arich is one single AV whose four Yuds bring forth AV, SaG, MaH and BaN. And each one of them must arrive at the meaning indicated by its root, which is the name of AV, and this is the strongest power they contain.
