First of all, it is important to understand that everything discussed in the Book of the Zohar, including even its Aggadot (parables), are forms of the ten sefirot, which are called Keter, Ḥokhma, Bina, Ḥesed, Gevura, Tiferet, Netzaḥ, Hod, Yesod, and Malkhut, as well as combinations of their forms. Like the twenty-two letters of the spoken Hebrew language, whose combinations are sufficient for us to uncover every object and every wisdom, so too the concepts and combinations of forms in the ten sefirot are enough to reveal all the wisdom in the book of the heavens.
