When a language is not connected with its spiritual root, we do not pay heed to its words, the names of the material branches. If a modern day Italian, Greek, or anybody else met a person of the same nationality who lived a thousand years ago, they wouldn’t understand each other. Some languages have changed so much that it’s hard to understand them in the form they existed 200-300 years ago. This is due to the lack of connection between branch and root.
Only Hebrew links branch and root directly, and hence, this language does not change. If Abraham, Adam, Moses, or Rabbi Shimon visited us today, we would all understand each other. In ancient times, the pronunciation was more guttural, which we have lost; the difference between the letters, which today are pronounced almost identically was more expressed, yet the language itself hasn’t changed.
Nevertheless, we have lost some of its words. Rabash used to read Psalms with me, and he occasionally mentioned that he was not familiar with a certain word. That is, their evident branch does not exist in our world; in the spiritual world, their spiritual root is still unclear and blurry, and for this reason, the connection between root and branch has not become revealed yet.
It turns out that we are yet to clarify certain words. For the time being they can only be found in the Psalms of David who embodies the entire general attainment (Malchut). Being dependent on the general correction, Kabbalists do not yet attain these words. There are a multitude of branches and corresponding spiritual roots, but not all of them have become revealed yet.
