Question: What is the difference in the perception of the Creator’s light between various people? Does it depend only on efforts or on some properties the Creator gives?

It seems that some people feel the light without making an effort and some, on the contrary, cannot come to feel it through their efforts.

Answer: The Creator reveals Himself in both ways. Therefore, we need to make efforts, and how the Creator advances us toward Himself is His business. The main thing is to ask Him to draw us toward Himself.

Question: Does the Creator hear our desires or the strength and effort in our desires?

Answer: The Creator hears everything, all our nuances, what we want to receive, what we turn to Him with, etc.
