“One does not try to impress anybody anymore and stops this dramatic play. One starts to feel it is not right.”
One of the ways I understand sakkaya ditthi is as such: when a person feels great importance and priority on whatever he is doing that can accentuate, flex, satisfy his ego, it is of essence, worthy to do it. To see it otherwise is sakkaya ditthi removed. In other words, a person who has sakkaya ditthi removed sees the fostering of his self ego being a futile effort. It can only bring forth more dukkha consequently if he strives to feed his ego.
Another understanding of sakkaya ditthi is to see there is no permanent unchanging self. Neither is there no-self after death. Got causes and conditions, effect arises. No causes and conditions, effect ceases to exist. It is like seeing a shadow of a coconut tree casted on the ground on a hot day. As the sun shifts position throughout the day, so does the shadow of the coconut tree. The shadow of the coconut tree appears to us that it has shifted over time. In fact, it did not shift. It is not stagnant either. Got causes and conditions, effect arises. No causes and conditions, effect ceases to exist.
