Accordingly we said that the coupling of the supreme Abba and Imma – which are Kindness-Judgment-Mercy only at root – is continuous, because Abba and Imma are in a continuous state of repair, being a revelation of the underlying unity of MaH and BaN (the perfection that must be attained in the end). Likewise all the benefits produced by their coupling are continuous.
However the function of Israel Sabba and Tevunah is to extend downwards for the sake of Zeir Anpin, and they are thus closer to the level of Zeir Anpin (which is subject to ascents and descents, immaturity and maturity etc.) The state of repair in Israel Sabba and Tevunah is accordingly not continuous. On the contrary, when there is no need for any new action – i.e. to generate new Mental Powers in Zeir Anpin – Israel Sabba and Tevunah merely transfer influence already prepared and rectified at root through the coupling of Abba and Imma to channel vitality to the worlds. In this case, the Mental Powers transferred by Israel Sabba and Tevunah derive from the previous coupling.
