throbbing light machine

What are we holding on to? I don't rightly know. I'm holding on to the only bit of light I've seen in these parts-you. I won't let that light go out, not if I have to fight the Dark Lord himself to keep him from blowin' it out. And every morning I wake up to see that light…well, it's all worth it for that. I love you, Mr. Frodo, and I'll always hang on to that. I don't know what you need to hold on to, but I'm right here, and you can hold on to me if you like.
