The picture of this world has to last throughout the entire process of our spiritual advancement until the World of Infinity. Our correction is possible only under the condition that we perceive the reality of this lower degree, our world.
We must continually attain roots that are above the picture of our world which we now perceive. This picture doesn’t change; it’s only that its roots become higher or deeper, meaning that we attain the Creator (the root of our desires) to a greater extent.
The picture we now see is just His branch that is depicted by our desires on the background of His desires. The world is the picture of our desires’ dissimilarity to Him.
Through the process of attaining, our language doesn’t change either, because the picture of the lowest world doesn’t change. We speak the same words regardless if we are on the first level, in the middle, or at the end of the path. Kabbalists don’t have any other possibility of communicating with each other besides “the language of branches.”
The lowest state is the same for everyone, and the connection from the branch to the root extends from the World of Infinity through the same line which we continue from one world to another, through all 125 levels and in all 613 desires.
Thus, we can talk about any desire on any of the 125 levels by taking the corresponding name of the branch from this world. This is why Kabbalists chose “the language of branches” – because it remains invariable along the entire path of spiritual advancement. It is a perfect language, and if we only knew the connection between the root and the branch, we would be able to understand it.
