Zohar 2:213b II

Jewish Mysticism
“When one worships his Master in prayer with desire and the intention of the heart, his will cleaves [to the divine] like a flame to coal, to unify those lower heavens on the side of holiness, to crown them with one name below, and from there to unify those inner, supernal heavens, so that all will be one in that supernal heaven that stands over them.”
