Maybe you enthusiastically shouted "Amen!" a few too many times, or perhaps you lingered a little too long on the "Modim" (we give thanks) during the Amidah. Turns out, there's a surprisingly deep reason why our Sages frowned on such repetition.

The Mishnah in Berakhot, Chapter 1, and Megillah, Chapter 4, both state that if someone says "Modim, Modim" (we acknowledge, we acknowledge) or "Shema, Shema" (hear, hear) twice, we silence them. Why?

The commentators explain that it can appear as if there are two authorities, as if the person is accepting two deities. It hints at a multiplicity that undermines the fundamental Jewish belief in the absolute oneness of God. As Rabbi Zeira said, according to the Talmud in Berakhot 33a, saying "Shema, Shema" is akin to saying "Modim, Modim." It’s about the impression it gives.

The Talmud in Berakhot 14a brings another example. Someone stood before Rava and said "Emet, Emet" (truth, truth) twice. Rava remarked, "Every 'Emet, Emet' that he said, he took hold of it." The idea is that truth is singular; repeating it suggests a division where none should exist. You can't say "Achad, Achad" (one, one) because it implies multiplicity, not unity. Truth, like God, is one.

So far, so good. Seems straightforward, right? But then… things get complicated.

The Zohar (Genesis 34a) delves into the mystical significance of the phrase "The Lord is King, the Lord was King, the Lord will be King forever and ever." The Zohar interprets this as referring to different aspects of God: "The Lord is King" refers to Erich Anpin (long of face), representing the Father and Mother. "The Lord will be King forever and ever" refers to the "small and female."

Wait a minute... isn't that sounding suspiciously like multiple divine entities? If God is crowning three "kings" with that one statement, how can we then say, "Our Father, our King, we have no king but You"? Haven't three kings already been crowned? Which one are we choosing to reign? And what happens to the others?

This is where things get thorny.

Rabbi Ba'al Ha'ikarim, wary of such interpretations, issued a strong warning: avoid studying the Zohar and other Kabbalistic texts without proper grounding! He cautioned against straying from the established paths of Torah, lest one become ensnared in their complexities. He felt that engaging in Kabbalah without the guidance of an authorized and accepted sage could jeopardize one’s pure and fortified faith.

Why such a strong warning? Because, without proper understanding, these complex ideas can lead to what seems like a belief in multiple authorities, contradicting the core principle of God's absolute oneness.

So, what are we to make of all this? On the one hand, we have a clear emphasis on the singular nature of God, reflected in the seemingly simple rules against unnecessary repetition in prayer. On the other hand, we have mystical texts that hint at a more complex, multifaceted divine reality.

Perhaps the key lies in understanding that Kabbalah isn't meant to be taken literally. It uses symbolic language to describe aspects of God that are beyond our full comprehension. The goal isn't to create a pantheon of deities, but to deepen our understanding of the divine.

Ultimately, the message is clear: approach these profound ideas with humility, respect, and a firm grounding in the tradition as transmitted by our Sages. Study with a qualified teacher, and always remember that the ultimate goal is to draw closer to the one, indivisible God. After all, the core of our faith, passed down through generations from Moses himself, is the absolute, unwavering belief in the Echad – the One.
