The monkey and the coconut

My kids are having to read "God's Smuggler" by Brother Andrew with John and Elizabeth Sherrill, this was in the book, a modern day parable. The story is in the India's and talks about the natives and catching monkeys to sale. This is to good not to share and it is a lot like what we do, when we don't want to give up something to follow God. Here it is:

"Do you know how natives catch monkeys out in the forest?"..."Well, you see, the natives know that a monkey will never let go of something he wants even if it means losing his freedom. So here's what they do. They take a coconut and make a hole in one end just big enough for a monkey's paw to slip through. Then they drop a pebble into the hole and wait in the bushes with a net."
"Sooner or later a curious old fellow will come along. He'll pick up that coconut shell and rattle it. He'll peer inside. And then at last he'll slip his paw into the hole and feel around until he gets hold of the pebble. But when he tries to bring it out, he finds that he cannot get the paw through the hole without letting go. And , ...., that monkey will never let go of what he thinks is a prize. It's the easiest thing in the world to catch a fellow who acts like that."....
"Are you holding on to something,...? Something that's keeping you from your freedom?"
