The effort and the attempt to understand the structure of the spiritual worlds, is not a theoretical understanding but a desire to feel, to live in them. Understanding can only be internal; just connecting the words in the mind gives one nothing without an understanding of their essence.
So the main thing is your efforts to be incorporated in these concepts and to begin to live within them, to enter into this system, into this matrix, or the opposite, that it will enter into you and “format” you, change you, according to the higher system. This is because you want to discover that you are acting according to its laws.
In the spiritual system these states change immediately, like a perfect and coordinated machine, but within a person many incarnations may pass between two small adjacent states.
The Klipa is like a rubber band that is inserted between the states and stretches them. The Klipa gives us a sense of time and doesn’t make it possible to erase the gap between the levels, between the states. If we were to nullify the Klipa, then time would disappear and all the states would be contracted into one action.
The ability of the person to advance and to develop depends upon how much he can pass through the force of egoism that gives him the sensation of time, movement, and space, to the Returning Light. In this way he nullifies time, movement, and space, and rises from this world to the spiritual state.
