A Phase of Immaturity and a Phase of Maturity 19. It has thus been explained that due to the ascent of Malkhut to Bina, two phases take place in each level: a phase of immaturity and a phase of maturity. With the ascent of Malkhut to Bina, Malkhut arrests the level there under Ḥokhma, and the Bina, Tiferet, and Malkhut of the level leave the level and enter the level below. Therefore, only the vessels of Keter and Ḥokhma and the lights of ruaḥ and nefesh remain in the level, and the level is consequently lacking the first three lights. This is the phase of immaturity (as stated above in section 17).
