NOTE: It is commonly believed that Astology is forbidden in Judaism. This is entirely incorrect, and comes from Jews learning about our Scriptures and traditions more from Christians than from our own Jewish sages. One of the giants of Jewish thought and Kabbalah was Rabbi Moshe Chayim Luzzatto (the "RaMChaL"), whose great writings are still studied to this day in literally every Orthodox Jewish Seminary in the world. Among them is his possibly most-important book, Derech HaShem ("The Way of God") in which he devotes an entire section to a discussion of Astrology in Judaism and Kabbalah.
Yakov Leib ha Kohain
7.1. In the first section (1:5.2), we discussed how every physical phenomenon has its roots among the transcendental Forces. When these phenomena are thus rooted in all necessary ways, they then must be reflected and transmitted to a physical thing in the required form.
It was for this purpose that the stars and their planets were created. Through their cycles, all phenomena rooted in the spiritual realm are transmitted and reflected to their physical counterparts. They can then exist in the terrestrial world in an appropriate form.
The number of stars, as well as the levels of their various divisions, were all designated as deemed necessary and most appropriate by the Highest Wisdom for this process of transmission.
The ability of all terrestrial things to exist is influenced by their respective stars. Through these stars, their essence is reflected from their aspect on high among the Roots to that here on earth.
