And what you wrote, who is the leader of all these hidden worlds? The one who created them is the one who sustains them. And what you wrote, that the Z"A is the God of the lower realms. Didn't I write to you that it is only a tool for the actions of the Creator?
And what you wrote, that some of them said that all of God's great deeds are included in a smaller category? Those who say so have already explained that their intention is referring to Metatron, whose name is like that of his Master, as it is stated in the Talmud: "And to Moses He said, 'Come up to the Lord'" (Exodus 24:1). Eli inquired, 'To me, He said, "Come up to the Lord"?' Rather, this refers to Metatron, whose name is like that of his Master, as mentioned in the Yalkut.
And what you wrote about our true Rabbis' statement, which is brought in Menorat HaMa'or, that during the giving of the Torah, the Holy One, blessed be He, tore apart the seven heavens, etc. And in Midrash Rabbah, they said, "I am the Lord your God, I am the first and I am the last. I am the first, having no father, and I am the last, having no son. Besides me, there is no God; I have no sibling."
Who claims to have a father or a mother or a sibling? Rather, you are spreading slander about the sages who affirm such statements. They have already explained their words, stating that all the appellations and descriptions are in the realm of the sefirot to accommodate human understanding. Please go and see what was written by Rabbi Yitzchak Gikatilla in the introduction to his book "Sha'arei Orah," as well as the divine Rabbi Menachem Recanati and Rabbi Yitzchak Chaim (may their souls rest in peace).
In conclusion, wherever you see matters that are not appropriate to ascribe to the Creator, such as measurements of height and similar concepts, it is all said in reference to the sefirot. However, when you see expressions of praise and acknowledgment, it is all said in reference to the Creator Himself, both within and beyond the sefirot, as nothing can limit Him. Therefore, one should not say about the Creator, neither right nor left, neither front nor back, and so on.
Please refer to the sources for further clarification. And regarding what you wrote about the opinion of the Kabbalists that the sefirot evolve naturally like a son from his father, perish the thought that they said so. On the contrary, they absolutely denied and rejected the belief or suggestion that the sefirot are separate entities from the Infinite One, who brought them forth and caused them to evolve from the highest level to the lowest.
Such a notion is a grave error. The Infinite One is not divided into parts, perish the thought, and He does not undergo any addition or subtraction. Rather, His existence is constant without any change whatsoever, and He constantly renews them with an absolute renewal.
