Beha'alot'cha: Chapter 1
"Which is like a bridegroom coming out of his chamber"

Rabbi Yehuda begins by saying that the children of Yisrael are blessed because God granted them the Torah of Truth, a Tree of Life, for all her words are life. He describes how the light of the sun, Zeir Anpin, illuminates and spreads from the top through the trunk, strengthening the right and then the left.
