I am fascinated by the ancient practice of capturing monkeys in India.  In this process, small cages with narrow bars are made and a banana is placed inside the cage.  The monkeys come along, reach in between the bars, and grab the banana.  Then the monkeys begin the impossible task of trying to pull the banana through the bars.  And here is the amazing thing, in the moment when the monkey catchers come along, the monkeys are totally free.  There is nothing keeping them from running off to saftey as they hear danger approach.  All they have to do is let go of the banana.  Instead, they refuse to release the banana and are easily taken into captivity.  

I ready this story in a book called, "The Yamas and the Niyamas," by Deborah Adele
