Answer: The moon is part of the Earth that must be outside of it to balance it. The wisdom of Kabbalah describes the nature of the planets and how the phases of the moon and the sun are related to us.
The Earth is between the moon and the sun, and if there were no moon, life on Earth would be impossible. We need this satellite, even science says so. From a Kabbalistic point of view, the sun corresponds to the Sefira of Keter, the moon corresponds to the Sefira of Bina, and the Earth corresponds to the Sefira of Malchut. The result is a triad: Keter, Bina, and Malchut.
Question: Is it possible to say that its own spiritual force operates on each planet and that it is specifically the spiritual root and not the astronomical body that influences people?
Answer: That is without a doubt! That is absolutely right!
