Question: My friend and I recently spoke about the order in studying the primary sources of the wisdom of Kabbalah and touched upon The Tree of Life. By drawing an analogy with musical notes, we came to a conclusion that Baal HaSulam presents this work as a symphony. At that, he is absolutely certain that The Tree of Life will be read by people well-versed in music, and there will be no secrets for them. And for the people who do not completely understand it, he wrote a simpler musical piece and called it The Study of the Ten Sefirot.
Does this mean that there is a group in Bnei Baruch where there is both: the internal part that knows about “C flat” and an external part?
Answer: We all need to advance together and not divide ourselves into parts, groups, or levels in any way. We all make up one homogeneous structure.
We will study what we study and you will begin to feel the material. You are right about the symphony where we all integrate in the general common tune, just like a musical instrument that the Creator plays on. We constantly aim and tune this instrument to a tonality increasingly closer to the Creator, and the Creator plays on it.
