“ And it is necessary that everyone give strength to the aspect of the Malkhut DiK'dushah (of Holiness) , to overcome the Malkhut DeSitra Achra (of the Other Side) , as our Rabbis of blessed memory said (Berakhoth 5) : "A man should always stir up the Good Inclination against the Evil Inclination." And how can he give strength to the Malkhut DiK'dushah? — through the Torah in which he involves himself vigorously (as our Rabbis of blessed memory said there: "A man should always stir up" etc. "If it [the Evil Inclination] leaves, good, and if not, let him involve himself Torah") . ”

“ And this is like Malkhut, which has nothing of its own, except what it receives from the Cheith, which is like Chokhmah, which is the aspect of the Sun as mentioned; "And the light of the Moon will be like the Sun's light".
[2] But whoever does not bind himself to the intellect, the wisdom and the life that there is in each thing, behaves like Esau who scorned the primacy, as it is written (Gen. 25) : "So Esau scorned his birthright"; that is, the intellect as mentioned above, like (Prov. 18) : "A fool has no delight in understanding, but only that his heart may lay itself bare." ”

“ And specifically Yosef was able to bless him with grace, for Yosef was the most made up from the essence of Ya`akov, as written (ibid. 37:2) : "These are the generations of Jacob: Joseph..." for he was the essence of his generations, for "Ya`akov and Yosef are counted as one" [Zohar] . ”
