Answer: You aren’t forgetting about it. Baal HaSulam has an article called “The Wondrous Quality of Remembering” which explains how it’s impossible to remember and then forget something. It’s simply that Reshimot are surfacing and passing in me.
Therefore, you shouldn’t be sorry about something you forgot from the past or something new that emerges that you don’t want. You have to accept every state as a working exercise and realize it. I need everything I have. I see myself after something has surfaced in me and I begin working from that point.
No matter what desires or thoughts awaken in you in order to confuse you with these unexpected “surprises” or infinite repetitions, they won’t go away until you realize them to the end, until you decide that this thought is not fit and you do not want to focus on it, or that it is desirable and you do want to realize it until the end. Nothing goes away until you make that final analysis.
The speed of realizing your desires and thoughts depends on your willingness to tolerate and ascend above them by working with faith above reason. In other words, it depends only on how included you are in the environment.
Question: Why do I have to tolerate this?
Answer: Because you are obligated to not run away from these desires, but to preserve them and analyze them, rising above them.
For example, I get some unpleasant thought. Then I become included in the study and the group, keeping a distance between myself and the disturbance that worries me. And I decide for myself that one is more important than the other. And I keep going that way until this bad thought gets discarded to the very bottom and disappears. That is how I analyze it. After that it keeps happening over and over again until I “trample” it completely.
