Answer: By listening to these melodies from time to time, they constantly find deeper, newer depths in it.
The point is that people who study Baal HaSulam’s method consider him their Teacher. They enter the world that he discovered and he leads them and reveals it to them. They follow him by studying his articles, letters, and multi-volume works many volumes, like the Talmud Eser Sefirot (TES- The Study of the Ten Sefirot) for example.
Professor Kfitza compared this book to a book of classic physics for the 11th grade by Landau-Lifshitz. He once told me that it is the basis of the spiritual physics.
In addition, Baal HaSulam’s most serious work is the Commentary to The Book of Zohar, which no great spiritual teacher before him could write for 2,000 years.
It is very interesting information that describes in the most accurate and special way the connection between the mind and senses when you have to examine your feelings with the mind and expand the mind with your feelings, which then helps you examine and clarify your sensations.
Thus you work in two lines: with the help of the line of your feelings you expand your mind and with the help of the mind you understand the new feelings that emerge in you. When they merge into one, the two lines help you feel the upper Providence.
Therefore, all of Baal HaSulam’s students feel these melodies differently with the new perception that is created in them, by the vessel of the upper providence, the sixth sense. They already play them on their developed emotions, with the help of the mind, and understand in their mind with the help of the new feelings.
The seemingly simple music of the upper worlds raises the deepest layers of emotions and new upper understanding in a person. It miraculously includes both the mind and the senses.
