And this tenth part, which is the aspect of the vitality of his Malchut, is called in the Zohar, in Parashat Lekh Lekha, page 83, Kista de-Chayei. That is, the measure of the vitality of ZA, for his root is only VAK, as is known — for he is the secret of the Vav of the Name — and his entire root is only VAK. And the measure of his vitality is called Kista de-Chayei. However, after the coming of the Mochin of Gadlut, then his entire vitality is added to him and completed in full.
