Answer: Our main work is concentrated specifically in the transition between the degrees, not in the fixed state. When I am on a certain degree, I work only in order to delve into these states, to understand and examine them.
In our world, we think that the main thing is the achieved state, not the transition to it. However, in the spiritual world, what matters is the transition, not the state itself.
We remain in a certain state only for the period of time required for us to discover it. It could last for a second, then the transition, again, a state lasting a second and again, the transition. There was a Kabbalist who told his students that he went through 400 ascents and descents in a few minutes’ time.
In the spiritual world, we feel an inverted and different dimension into which we break within the framework of time, movement, and space. It is specifically by this that we penetrate the space between the seconds of our world. In our world, the seconds move directly one after another. Spirituality is found between them because spiritual life takes place specifically in the transitions, not in the states themselves.
A static state is a dead one, and it doesn’t count in spirituality. It exists only in order to complete the degree, which includes in its sub-degrees a great many internal transitions. This is why a person, who is in the spiritual world, is constantly going through changes and has no rest.
The spiritual concepts do not exist within our coordinates of time, movement, and space because in our world, there are no breaks between the seconds, there are no gaps either in time or space. Whereas spirituality indicates that you find an interruption between one second and the next, and penetrate its depth, thus entering the spiritual dimension.
