How to trap a monkey:

You secure a gourd to a tree and drop some shiny things into it. The monkey spots the gourd, peers into it, sees the shiny things and sticks his hand into the gourd and grabs the shiny things with his fist, but the narrow neck of the gourd prevents him from pulling his fistful of shiny things out. So he is trapped.

Alas, the poor little primate does not have the intelligence to simply LET GO of those shiny things and FREE himself.

How you DEFINE yourself, is how you LIMIT yourself. To hold something , means you can drop it, to believe in something means you're stuck with it (Just like the monkey).

You put the LIE in beLIEf.
