It is only in the case of BaN, which does not have its own particular AV, that the AV contained in the fourfold form of the simple name is considered intrinsic to it. This is as we have explained, that even BaN does not lack the presence of AV in some way, despite the fact that it does not have its own particular AV.
Part 2: This shows... As I have written, the various numerical values are not arbitrary and without reason, but show a great deal about the different orders of government.
...that each one of them has an equal meaning at the outset, even in its simple aspect... For as soon as they exist, they already give an indication of their root, in that the start of their existence is as four names of Havayah, for this is how they are implied in Arich Anpin in four Yuds all equal to each other, and this is in their aspect as being lights – branches – of Arich Anpin. (The four expansions of Havayah derive from the four Yuds contained in the expansion of the overall AV – Yud, HeY, VaYV, HeY.) However, because each one has its own particular function, they all have their own individual filled or expanded forms. The intention is indeed to show that even though they are different levels, in the end they are all only the name of Havayah, blessed be He. If so, their original essence is the primary category – the name of Havayah, blessed be He – but afterwards they receive additional individual functions. The filled or expanded forms themselves indicate the particular function that each one has.
