Part 16 · Chapter 246

And now let us explain their matter. Know that although in all four worlds there is the aspect of Klipot, there is a difference in the worlds themselves. For behold, in the world of Atzilut of holiness, the good is more abundant than the Atzilut of impurity, and holiness is not mixed with impurity at all. And in the world of Beriah, holiness is more abundant than the impurity of the Klipot of Beriah, however, they are mixed together. And in Yetzirah it is half and half, and also good and evil are mixed together. And in Assiyah, the Klipa is more abundant than the Assiyah of purity, and they are also mixed together. And there is no thing in the world of Assiyah that is not composed of good and evil: holiness and Klipa mixed together literally.
