Immediately on coming forth from Imma, Zeir Anpin is in fixed possession of Chessed-Gevurah-Tiferet, and we say that Chochmah-Binah-Daat are in the process of coming. (To summarize: The different periods are not named after what is under repair but rather after what has already been repaired. At the beginning of the Pregnancy Netzach-Hod-Yesod are complete, and accordingly the entire Pregnancy is called Netzach-Hod-Yesod. At the moment of birth, Chessed-Gevurah-Tiferet are complete, and accordingly the entire period of Suckling until thirteen years is called Chessed-Gevurah-Tiferet. At thirteen years the repair of Chochmah-Binah-Daat is complete, and the ensuing period is therefore called Maturity, גדלות, gadlut and Chochmah-Binah-Daat.)
