You can protect yourself from misfortunes sent by Heaven,
not from misfortunes that you bring on yourself.
My Buddhist tear-off calendar recently displayed the above quote. I kept it on my desk for a few days, then recycled it. This morning, I dug it out of the recycling bin.
Today, I know that my brain is creating problems that don't exist, judging people who need to be shown grace (including myself), and generally being a jerk.
I haven't had much success getting my internal self turned around so far today, but I am going to reread that quote throughout the day and remind myself how much power I have over my own experience. And when negative thoughts arise, I'm going to do my best to acknowledge them, let them go, and move on.
So say we all.
