Question: Attainment in spirituality occurs only in reflected light. How can one construct the most elementary level of reflected light?

Answer: The level of reflected light must correspond to the direct light that descends from the Creator down. The reflected light must be the same as the direct light. Then they will be equivalent, and the creation that receives the direct light in the reflected light will fully understand all the definitions in the direct light.

Question: But I do not want to receive anything for myself. I only want to give something to the Creator. How do you do that?

Answer: You must understand how to make a screen for yourself and from this screen become like the Creator in the reflected light. Then, being like Him, you will understand His actions and state and merge with Him. This is the action of the screen.

Question: But how does this translate into intention? What should I be thinking about?

Answer: Your intention and focus should be about being in likeness with the Creator.
