We can sometimes make our experiences very solid and permanent. This gives them more importance and increases our tendency to become identified with their energy, and get stuck in the story, causing more suffering in this way.
Transience is the force of time that makes a ghost of every experience. There was never a dawn, regardless how beautiful or promising, that did not grow into a noontime. There was never a noon that did not fall into afternoon. There was never an afternoon that did not fade toward evening. There never was a day yet that did not get buried in the graveyard of the night.
In this way transience makes a ghost out of everything that happens to us.
