I can gnaw on a thought for a long time. Like some old pit bull, I can lie around worrying some bone I have to pick with someone for a long time. I can spend a lot of my life being right.
The question is this, though, "how much energy am I wasting being right?" Is it worth it to be right this long? How much of my life passes by with me worrying, fighting, obsessing, feeling sad and unworthy? Is there another way?
Yoga offers some wisdom about this. In the Yoga Sutras (a 2500 year old book of poetry in Sanskrit that is something like a bible of yoga), there is a verse that talks about this.
