Question: Why is it said that light is at absolute rest if our entire path is accompanied by the light entering desire and exiting it?

Answer: The absolute rest of the upper light is its constant change with infinite frequency! The “unchangeability” of light means its rest, constancy in achieving a single goal, for it always performs only actions that lead to it. Its absolute rest lies in the fact that it does not change this goal, but acts toward it with infinite speed.

For us, rest means not getting entangled along the path, but striving in one direction and seeking for thousands of ways to advance there, keeping intensity and applying efforts. And all this is called absolute rest because I see a single goal before me.

Light enters into desire and exits it, and every moment its infinite number of actions take place. But if a person is in the quality of bestowal, then he feels all these various actions as eternal rest!
