Quote: or maybe, to put it a little more accurately: I feel as if sometimes the external world or real events can make me unhappy (though often my unhappiness is mostly or wholly self-generated.
Hm. Interesting. So you are saying that your natural 'state of being' is happy and peaceful, and the external world and its events can throw your natural state into kilter.
And because the world is an unpredictable place, it is impossible for you to determine how your happiness and peace may be affected on any given day.
Would you say this is accurate? Don't worry about me... I'm just trying to crawl into your head and get a good idea of how you view all this. I do have a point, believe it or not, in asking you these questions. I just need to be sure we are seeing this in the same way before I get to it.
