…and all the other aspects of Zeir Anpin are governed accordingly. As already discussed, the strength of the rest of the body depends upon the strength of the Mental Powers.
By the principle of gradation it is not proper that he should receive any more than this at that time. (Malchut of Abba and Imma subdivides at that time because Zeir Anpin is unable to receive all of Malchut of Abba and Imma, i.e. the First Israel Sabba-Tevunah, but only Malchut of the latter, i.e. the Second Israel Sabba-Tevunah.) This is something that changes at different times: the First and Second Maturity come about because of the unique nature of the holy days as opposed to the weekdays. There is thus a difference between the levels of Pregnancy, Suckling and having Mental Powers on the one hand and the First and Second Maturity on the other. The periods of Pregnancy, Suckling and Mental Immaturity come to complete the building of the lights so that they can function according to the needs of the world. However the First and Second Maturity come when the lights are already built and complete but can function with either more or less strength. We must call this a difference in the degree of their importance and functioning.
