“Letting go” actually means this: It’s as if we’re carrying a heavy rock. As we carry it, we feel weighed down but we don’t know what to do with it, so we keep on carrying it. As soon as someone tells us to throw it away, we think, “Eh? If I throw it away, I won’t have anything left.” So we keep on carrying it. We aren’t willing to throw it away.
Even if someone tells us, “Come on. Throw it away. It’ll be good like this, and you’ll benefit like that,” we’re still not willing to throw it away because we’re afraid we won’t have anything left. So we keep on carrying it until we’re so thoroughly weak and tired that we can’t carry it anymore. That’s when we let it go.
Only when we let it go do we understand letting go. We feel at ease. And we can sense within ourselves how heavy it felt to carry the rock. But while we were carrying it, we didn’t know at all how useful letting go could be. ~Ajahn Chah
