Often, in spiritual teachings, you hear things like "let it go." However, for people who haven't done much training, the ego is still strong. When you're told to "let it go," the ego interprets that as an instruction, and conversely, it can strengthen the attachment, leading to a counterproductive effect. The person explaining may be explaining things correctly, but the person understanding it interprets it in their own way, which can lead to a counterproductive result.

Physically letting go of something is something you can do if you want, but if you don't intellectually understand it, it's difficult to let go of things. Intellectually letting go, in reality, thinking strengthens itself. So, even if it's "letting go," for people with a strong ego, the more they think about something, the stronger the attachment becomes. As the attachment becomes stronger, letting go of things becomes even more difficult.

In this way, the more the ego intends to let go, the more it thinks about it, and the stronger the attachment becomes, leading to a vicious cycle.

As a basic principle of meditation, there's the idea of "not following thoughts" and "simply observing thoughts." In reality, being able to do that comes after you've become somewhat accustomed to meditation, and are at an intermediate level or higher. However, for people who haven't meditated yet, the difference between thoughts and observing them is often not well understood. In such cases, even if you think you're letting go of thoughts, you're actually caught up in them. Or, your thoughts might cleverly deceive you, saying, "I'm meditating well," "I'm observing well," "I'm letting go well," and as you progress in meditation, you realize that this is just an excuse from the ego. However, if you haven't trained much, you might strangely agree with it, thinking, "Yes, I'm meditating very well."

Therefore, while "letting go" is indeed something that exists in spiritual teachings, I've always felt that this "letting go" didn't quite resonate with me, and I've felt a sense of unease with what others are saying about "letting go." Recently, I suddenly realized, "Ah, that's what it is."

Recently, "letting go" has become a popular "guideline" for action. However, I personally interpret it as not a "guideline" that becomes a trend, but simply a "result."
