Answer: I have the line of the Light and the line of the vessel. I build myself as the third line between them. I take as much as I can from the desire to receive and from the Light and build the final form, the sum of these forces (Σ).
This form is a human being. Even though the components are not mine, I have to combine them and decide the right combination. I decide this myself.
To do that, I first have to feel the shame that I do not resemble the Giver, determine the working material, and find the force that corrects it. I am required to create a human being within me, to desire that he become formed. I already have the forces and material. I have only to check the form, and I perform this check every time on the 125 degrees of similarity to the Giver.
I check myself relative to the upper one and identify my abilities. This is a very big job. Thanks to it, I begin to accept, feel, and understand Him. I “format” or “draw” myself in search of exact solutions. As a result, I become like the Creator, not according to superiority, but according to bestowal. In receiving in order to bestow, I make myself similar to Him.
