Repentance helps only on Malchut that is sweetened in Bina, when there is a time of Katnut [smallness/infancy]. In Gadlut [greatness/adulthood], the AHP return to the degree. “Returning” means that they can be used in order to bestow. This is considered that repentance helps, meaning that we can correct, that it is possible to use vessels of reception.
This is not so with the AHP, which belong to GAR, which can shine only through the correction of Malchut in her place. But since Malchut was concealed in RADLA, here repentance does not help, meaning that he cannot return the AHP to the degree before the end of correction.
