Answer: Hebrew is a mathematical language. It is the opposite of other languages.
There are two forces in the universe: the light of Hochma and the light of Hassadim. Their interaction is the basis of the future Kli (vessel). That is, the light is at the root of everything.
The root of Hebrew words can consist of one, two, or three letters. This is either one line, two lines, or three lines. The letters cannot arbitrarily be combined with each other, like in other languages according to their rules. Here there are no rules but laws of nature, laws of the world.
The binyan is the basis, the structure of the word, which always clearly expresses its root base: a combination of lights and desires. After all, what else is there? The light is from the Creator and the desire, that is, the intention, reflected light, is from creation.
It all depends on what state they are in. It can be only one, two, or three lines. Therefore, as a rule, we have two lines, and in special cases— three. It speaks only of the basis of the word.
All these questions are clearly mathematical. There can be no arbitrary movements.
