In the beginning of the commentary on Beresheet the Zohar reveals a secret that the Holy Ari and Rabbi Ashlag based their study of the Tree of Life and Ten Luminous Emanations.
From the Endless Light came out a spark of Light that created empty space for the creation of the worlds. This spark is the aspect of Judgment that the entire existence is held by it. It’s the system of cause and effect. From that point on, every step in the creation, the process was more limited than the previous one.
The first spark of light had no color but from it came different shades of colors that represented the different sefirot. The first colors were white (Chokmah), Red (Binah), Green (Tiferet) and Black for Malchut.
Here are few notes I published in the past about the initial process of creation.
The Creator, Bless be He, raised a ‘desire’ to create a place to build a special ‘home’ for his created beings. A place with a spiritual system that is an extension of him. In this place, he would build physical worlds and to bestow on his special beings the ability to control their environment and be like him.
Before the Creation, there was only simple light that filled the entire existence. Since we cannot define it or know anything about it we call it the Endless, Bless Be He.
To create this “place” “המקום”, the Endless light distanced himself (its light) from the middle point, equally to all directions. This process created an empty sphere “חלל ריק”
The ‘emptiness’ of this space was not void of light but it was a state where the light was concealed in a system and process. To understand the principal we look at the sun as a source of Light. We cannot come too close or look at it directly. Its light cannot be seen in space but we know that it exists everywhere and is reflected from anything on its way.
The creation of the empty space is called ‘Tzimtum’ and the literal meaning of this word is ‘reduction’. The Endless light reduced its presence in the sphere to make a place where his powers could be revealed.
The missing light created a state of darkness that is the root of the forces of judgments. The lack of light also created something that was never there before and it was the vessel.
Having something and experiencing lack creates a vessel, which is a desire to restore the light that was there before.
The benefit of this aspect of Creation is that now we can have a drive to fulfil our vessels.
The sphere could not stay in the dark so in the next step the Endless continued a thin line that is like a pipe from the Endless all the way down but it did not touch the other end of the sphere.
Why didn’t the line go all the way down?
The endless surrounds the sphere and if the line were to touch the other side it would have flooded the sphere with the Endless light and would have voided the existence of the sphere and its identity as a ‘vessel’.
If two elements become equal they ‘merge’ into one and we can not see differences between them. Simple example is a cube of ice that comes in touch with water. Once the ice melts into the water, we cannot see it.
