Recently, I still occasionally experience the sudden resurgence of painful memories from the past. However, now it's usually just a single, clear instance, and after that replay ends, I quickly forget it. I'm so clear-headed that I often can't even remember what I was thinking just minutes or even a few dozen minutes before. While I know I was remembering something, I often can't recall the specifics. The past memories are replaying only once.

A while ago, the memories would linger a bit longer before fading. But now, it's mostly just a single instance, and at most, I might recall various related things for a few minutes or up to about 20 minutes before the memory fades completely. It's hard to define what constitutes a "single instance," but it's definitely more than once. While I might say it's only happened once from a certain perspective, memory replay involves looking at things from various angles. I might replay the same topic multiple times, perhaps 10 or fewer, from different perspectives. Once I've seen everything from all angles, I'm satisfied, and that's the end of it.

In the past, especially decades ago, I would repeatedly experience traumatic images and memories for days, weeks, or even months, forced to endure extreme tension and conflict.

Even about 10 years ago, the replays were still fairly frequent.
About 5 years ago, the frequency decreased, but the replays still occurred.

Until recently, the replays were still happening, although much less frequently.

Now, even when memories resurface (occasionally), the unpleasant feelings associated with them are usually short-lived. The painful memories, even those that were once traumatic, are re-experienced briefly, and then they fade away.

This could be described as "letting go" or "healing." While I'm surprised that remnants of these painful emotions still linger with these memories, it's also a form of attachment. When these painful emotions, especially those felt in the stomach, arise, I intend to "let them go," and I say those words. These are old emotions that have been repeated hundreds, thousands, or even tens of thousands of times in old memories, so they are no longer needed, and I declare that I am letting them go.

And, in reality, that's what happens. There are lessons to be learned from these conflicts, but after countless replays of the memories, the lessons have been learned, and the unnecessary memories can be let go.

Some of the lessons include:
- Not accepting other people's values. Refusing to accept other people's (self-centered) judgments or impressions of me (that I, unintentionally, accept).
- Eliminating the state of being "too lenient."
- For example, classmates who constantly belittled me were (too low-class) for me to even bother with, and I have no reason to (retaliate and) insult them (because retaliating and insulting would bring me down to their level). There are countless low-class people in the world, and it's important to associate with people who are your equal.
- I don't need to feel bad for people who belittle me. (I don't need to feel bad for those people, and) those people are not worth my sympathy. (There's no need to do anything for those people, and they're not worth me feeling sorry for. There are people in this world who are so low-class that even a brief interaction with them is a waste of time, let alone spending time and effort to make them feel better. They are living their lives in a low-class world, belittling others, so they can live as they please, but they should not involve me.)

For example, the memories that resurfaced yesterday were from a high school math class, involving a teacher and classmates who belittled me. Because I realize that there's no value in interacting with such people, this is how it happens.

- The lesson I learned was something like that (reaffirming the lessons associated with the memories).
- Now that I've learned the lesson, I'm "letting go" of this old memory. I declare it, and it actually happens.

For any past actions, there's likely a lesson to be learned. Once the lesson is learned, the various painful emotions associated with the old memory can be let go.
