In Africa they have a special way of capturing monkeys.
These wary little animals are very fond of rice.
In order to capture them, local farmers put some rice inside a hollow coconut shell, into which they have cut a hole just large enough for the monkey's hand.
Half a dozen traps like this are left lying around in the center of the village. But each one is attached by a string to a nearby house.
A family of monkeys comes up, attracted by the smell of rice. Each slips its hand into a shell to get a handful of rice.
But with its hand full, it is unable to remove it. The hunters then approach and easily gather in their prey. If the monkey would only let go of the rice, it would be able to get away from the trap that had been set for it.
But it likes rice too much to give it up - even at the risk of life.
How true it is, that the hand which is closed cannot receive - even freedom.
