grasp the central point

All you can do is to grasp the central point, that reality is not an event and does not happen and whatever happens, whatever comes and goes, is not reality. See the event as event only, the transient as transient, experience as mere experience and you have done all you can. Then you are vulnerable to reality, no longer armoured against it, as you were when you gave reality to events and experiences. But as soon as there is some like or dislike, you have drawn a screen.
