...and this is the strongest power they contain. For the fact that the root is visible in the branches shows how the root and branch are joined together. Clearly the strongest power in Abba and Imma, Zeir and Nukva is the fact of their being attached to Arich Anpin, which is the root. There are two reasons for this. Firstly, since the root is the source, as long as the branch is attached to it, the root sends into it a great power of endurance. Secondly, since Arich Anpin itself is the great and awesome root that is beyond the reach of any flaw or damage – because the Other Side does not reach there in any way – accordingly, when Arich Anpin radiates in the branches, its attachment to them certainly puts great power in them through the very great power which it possesses.
