We must imagine the spiritual world as an empty vacuum. On one side of this empty vacuum is the person, and on its other side is the Creator, and within this emptiness that separates us, we begin to build all kinds of connections, sections, and forms that connect us with the Creator.
We fill this space with our thoughts, desires, and intentions regarding the Creator with all kinds of observations about the force of desire: Shoresh (0), Aleph (1), Bet (2), Gimel (3), Dalet (4). This means that we construct different sections within this space, forms closer to the Creator, like an internal spiral, cubes, pyramids, and all kinds of geometric forms.
All of these forms are constructed from thought, our intention to reach the Creator in all kinds of ways since in every phenomenon four phases are found, all of the restrictions. In the meantime, we are not prepared to rise above them, so they create the form of HaVaYaH.
However, after we reach the completion of correction, all of these separate forms disappear in that they are connected into an integral form that fills this space with an infinite connection with the Creator, which is no longer in various separate forms but merged together into one whole.
