Answer: Certainly! After all, time is defined as a chain of the informational genes (Reshimot). You can travel along this chain from the beginning to the end and go wherever you want. If you possess the anti-egoistic screen, meaning the ability to exist in any state, you can choose any Reshimo and realize it.
Obviously, no one would want to descend back from an advanced state. This wouldn’t make any sense unless you had to descend for some period of time in order to help others, that is, to go back in order to establish a connection with them.
However, I would perform this “reversing” through the special Partzuf called “hair” (Searot). I myself stay in the advanced state, but I make a “smaller” copy of myself through which I communicate with those who are below me.
However, one cannot descend for no reason because it contradicts the purpose of creation. How is it possible for a spiritual individual to do such a thing?
