So where does the division of the text come from? It is caused by the fact that we are so small that we are unable to accept everything and incorporate it within us. Therefore, the more we advance and the generations develop from the time of the Torah’s and The Zohar’s composition, the more we need to divide the text into parts, paragraphs, and chapters with titles. After all, it’s very difficult for us to take in rows upon rows of letters, to look at them and become similar to them in our intention. But this is, indeed, the work of correcting our desires, and its order determines the structure of the Kabbalistic Prayer Book.
This is why Baal HaSulam divided all of The Zohar into paragraphs and chapters. In addition, he wanted to add introductions, definitions, and clarifications preceding the text. In doing so he wanted to balance the text of The Zohar with his Sulam Commentary in a way that doesn’t just offer explanations, but designates the middle line in The Zohar’s text. Without his commentaries, we wouldn’t be able to balance the text inside us in order for it to clothe inside us correctly in the middle line.
Thus, Baal HaSulam doesn’t offer us mere explanations, but causes us to oscillate while reading the book, thereby attuning our vision, approach, and sensation in a way that makes them go through the middle line, “the golden middle.” Therefore, we have to accept all the commentaries with gratitude regardless of whether they are short or long. We have to go along with them and understand that we are building our middle line in this manner.
This is what the Sulam Commentary is intended for. Without it, The Zohar is only two lines, just like the rest of the Torah. We have to build the middle line ourselves, and the Sulam Commentary helps us do this. This is why it is called “Sulam” (Ladder). It is already built in the form of steps, and all that remains for us to do is to climb them. The ladder is already there, and now we just have to make efforts to climb it. We must only push ourselves forward slightly and we will be sure to follow the right path.
This is why Baal HaSulam writes that after the composition of his “Sulam Commentary to The Book of Zohar,” he is certain that it is impossible for a person to err. One will go through a wondrous spiritual ascent and thereby attain the revelation of the Messiah – the Light of Correction.
