There are no vowels in Hebrew. They are expressed by additional dots and marks above, below, or inside the letters.
The Hebrew letter consists of three elements: a dot, a line, a circle.
This point can express a circle and can expand in any direction from four sides (meaning movement on a plane).
We can talk about this endlessly because the movements of a black dot on a white background express the entire spectrum of the attitude of the Creator to creation and conversely, the creation to the Creator.
That is, the shape of some letter on a black background expresses how I perceive the Creator’s influence on my Kli (vessel). The white light is the light of bestowal, love, and unity with the Creator. As I feel this light, I perform some actions with it and send it back to its source.
We need to study all of this.
