A word from Buddhism, the consciousness of "unintentional self-liberation"?

For example, it is very painful for a person to be unable to sleep because of insomnia. He tried every means: for example, he thought he would fall asleep, for example, he kept counting sheep, for example, he gave himself all kinds of psychological comfort, but he still couldn't sleep. In fact, don't leave the idea of "insomnia", so that you won't suffer or toss, but you will fall asleep naturally.

The same is true of practice, clinging to an achievement or a liberation, in fact, practice has not increased anything. One thought of good, one thought of evil, one thought of quietness, one thought of boredom, and unintentional self-liberation.
