Baal HaSulam, The Study of the Ten Sefirot, Part 1,“Table of Answers for Topics,” Question 56: What is the ordinary language in the wisdom of Kabbalah?
This language is a “language of branches” that points to their upper roots. That is because “You haven’t even a single blade of grass below that has not a root above.” Therefore, the sages of the Kabbalah have put together a language that is equipped to imply through the branches and teach of the upper roots.
There are no words that we hear or read in Kabbalistic books that don’t lead us upwards! In this world, we are able to express any concept in various ways: hearing a word, seeing it written, or saying it out-loud, but the essence of the word will still point to its root.
In other words, the language of branches doesn’t represent the root or constitute its material branch, but rather it shows us the attitude of the branch towards the root. Each word points from the bottom to the top, meaning from the property of reception to the property of bestowal.
Obviously, the words “down” and “up” do not imply position in space, but signify qualitative notions. When perceived in the correct way, each word always tends to move us from the state of reception to the state of bestowal. The more we penetrate each word, the more it elevates us towards the state of bestowal.
