Things like this are a part of our enlightenment. For example, if a particular student who has a habit of always being late changes his orientation and starts being on time, that changes his whole life. It's like a container of water. If you pour a few drops of bleach into the container, it changes the whole composition. If you have difficulty being on time, and then you're on time, the whole structure of your delusion will begin to change. That's a definite part of waking up.
