When still a baby, the elephant is tethered by a very thick rope to a stake firmly hammered into the ground.
The elephant tries several times to get free, but it lacks the strength to do so. After some time, the animal gives up trying, believing that it cannot be free.
At this point, the trainer changes the thick rope to a thin one but the elephant makes no attempt to run away. Even when the elephant reaches adulthood, it continues to be tethered by a thin rope, reconciled to its captivity.
As WE grow up and gain experience, WE absorb assumptions which then drive your life and limit OUR choices. They are similar to the elephant’s thin rope tied to a post WE can break away from them with a simple tug if WE want to but WE don’t.
