…it is Israel Sabba and Tevunah that give the Mental Powers to Zeir Anpin through their Malchut, which is called the Second Israel Sabba-Tevunah, and the latter clothe themselves in Zeir Anpin’s Tzelem in the same order as above. These are called two levels of Maturity… They are two kinds of Maturity, yet they both follow the same pattern. The Mental Powers that come from Abba and Imma (i.e. in the Second Maturity) are primary, as opposed to the Mental Powers given by Israel Sabba-Tevunah, which are the bottom part.
