The Language of the Kabbalists Is a Language of Branches
The language of Kabbalists is a language in the full sense of the word: very precise, both concerning root and branch and concerning cause and consequence. It has a unique merit of being able to express subtle details in this language without any limits. Also, through it, it is possible to approach the desired matter directly, without the need to connect it with what precedes it or follows it.

Thus, Kabbalists have found a set and annotated vocabulary, sufficient to create an excellent spoken language. It enables them to converse with one another of the dealings in the Spiritual Roots in the Upper Worlds by merely mentioning the tangible branch in this world that is well defined to our corporeal senses. The listeners understand the Upper Root to which this corporeal branch points because it is related to it, being its imprint.
