Yes, I understand, this is easier said than done. But it took me a long time to even think this...
We must embrace the world, and let go too. It's kind of a Zen-like idea. We must open our minds, open our arms, and embrace the things of this world. And hold tight. But then we must let go. Let everything slip out of our embrace, just let it all slip away. And the real trick, and I'm not even sure it's possible, but it's what we should shoot for - we must embrace and let go at the same time, all the time.
