A wonderful metaphor for the ordinary workings of the mind. Oh, and you know how to catch a monkey don't you? Thru a small hole in an empty coconut put a few nuts or some fruit. Chain the coconut to a stake. Soon a monkey will investigate and put his hand in to make off with the treats, but his little balled fist won't fit thru the hole. Neither will he let go. Contrast the mind and with its vaunted reason and treasured ideas.
