In answer to questions regarding the verse, "And these are the names of the children of Israel," Rabbi Yehuda explains the title verse, "I am black but comely..." This, we learn, is a reference to the Shechinah who is described as "black" because the children of Yisrael are in captivity, but "comely" because they cleave to the Torah and good deeds. For this, they will inherit the heavenly Jerusalem.
The Zohar emanates spiritual forces that end our personal and global Exile upon the merit of the Torah's awesome powers. The Heavenly Jerusalem becomes our world, a place of boundless blessings and endless fulfillment.
Any area or aspect of our personal life that is in exile or darkness is redeemed and eternally illuminated.
