Similarly, the world of Atzilut, which is the mystical meaning of Ḥokhma, which is entirely Divinity, is comparable to the white in a book. That is, we have no grasp of it whatsoever; rather, the entire manifestation in the book of the heavens is in the sefirot of Bina, Tiferet, and Malkhut, which are the three worlds of Beria, Yetzira, and Asiya. For they are considered the ink in the book of the heavens, whose letters and combinations are manifested through the three aforementioned types of ink, and it is only through them that the Divine light is revealed to the recipients.
