This too is through a gradual process and not by going from one extreme to the other so as to have either the whole of Malchut or only the lowest part of it. After receiving the lowest part, Zeir Anpin ascends gradually level by level until he receives it all. First he receives Chessed-Gevurah-Tiferet of this Malchut and afterwards Chochmah-Binah-Daat. We then say that Zeir Anpin has attained the Second Maturity. For with the entry of Chochmah-Binah-Daat, the entry of the whole of this Malchut is complete – the entire Tzaddi of the Tzelem is within Zeir Anpin. All the upper levels of the First Israel Sabba-Tevunah then remain as his Lamed-Mem through the mystery of the Second Maturity.
Spiritual Growth as a Slow Unfolding
