When watching a movie I saw school kids destroying their school. It came to my attention that they were doing so because they subconsciously blamed the things in school for the dislike of all school. When they break everything, it changes its appearance and therefore their sensual memory of sight does not access unwanted feelings because they do not see the same sights.
When the perception changes the memories cant be accessed directly because the trigger was destroyed. The trigger being the usual perception of school. since the bad feeling taking you farther from the womb is gone they feel the goodness of the womb that we define as liberation.
This concept of course can be applied to any sense. The main purpose of this paper though is to explain the mentality of one who enjoys the act of destruction without having a direct unwanted memory of the thing that they are destroying.
As explained above, the act of destruction is the act of changing an objects perception so it does not access unwanted memory.
