Kabbalah zu Kohelet 1:6

And come and behold, although the sun illuminates the whole world, it travels in only two directions, as it is written, "goes towards the south, and veers to the north" (Kohelet 1:6), for south is the Right and north is the Left. And the sun rises every day from the east side, and travels toward the south side. It then veers to the north side. And from the north it veers toward the west. Then the sun moves to the west, where it sets. The sun rises in the east, as it is written, "And Jacob went out from Beer-Sheva,". The sun goes west as it is written, "And went toward Charan." This teaches us that the illumination alluded to in the text, "And Jacob went out," is a complete illumination comprising the two Columns, Right and Left, which is the secret of Chochmah and Chassadim combined.

Rabbi Yitzchak began the discussion with the verse, "The sun also rises and the sun goes down and hastens to its place where it rises again" (Kohelet 1:5). "The sun also rises," refers to the sun, which shines on the moon. For when the sun is seen by her, she shines, illuminates and shines from the supreme place that is above it, from where it always rises. "And the sun goes down," means that when it comes to mate with the moon it "goes towards the south" (Ibid. 6), which is the Right and there reposes its strength, because its strength is in the right. As a result, all the strength of a man's body is in the right side, from which stems the strength of the body. Later, "and veers to the north," and shines upon this side and shines upon that side. "Round and round goes the wind" (Ibid.). Why is it first written, "sun," and now "wind." All is one secret. And all this happens so that the moon will illuminate by its light and the two will join.
