On the way to yoga today, I had a thought which, I thought, when I thought it, that's quite a wise thought. And this is what I thought:
If the basis of your current feeling of happiness is based on something outside of you, drop it**
This might sound a bit extreme to most people who have no interest in Zen. It's pretty common to hear of people saying to let go of harmful feelings or worries though. But all these buildings we create with our thoughts and feelings will fall no matter what they are, happy or sad. And by drop, I don't mean, get rid of...just don't keep on thinking them, building upon them, turning them into megastructures upon which you base your life. Which is what I tend to do...
This is probably inspired by Kosho Uchiyama's Opening the Hand of Thought, which is pretty much the best book on Zen I've ever read. To paraphrase...no, I won't, just read it yourself.
*Originally my metaphor was blowing up a balloon, but deleted that and went for a building, but forgot to delete the title.
**I have to add a disclaimer to these sorts of posts. I like writing about these sorts of things but am often talking rubbish which I look back on and think, ooh, that's stupid.
