…to Abba and Imma… i.e. together – for the nature of Abba and Imma is to be equal in the sense that the receiver is still on the same level as the giver of influence and not on a lower level as is the case down below, where the Nukva is beneath Zeir Anpin. Abba and Imma are able to stand on the same level because here the receiver is in a state of repair. This is because any damage caused by the lower creations does not reach as far as Imma, making it possible for the receiver to stand on the same level as the giver of influence.
Father and Mother as Divine Archetypes
