Elizabeth Gilbert, author of "Eat, Pray, Love" muses on the Quest Physics: In the end, I’ve come to believe in something I call “The Physics of the Quest.” A force in nature governed by laws as real as the laws of gravity. The rule of Quest Physics goes something like this: If you’re brave enough to leave behind everything familiar and comforting, which can be anything from your house to bitter, old resentments, and set out on a truth-seeking journey, either externally or internally, and if you are truly willing to regard everything that happens to you on that journey as a clue and if you accept everyone you meet along the way as a teacher and if you are prepared, most of all, to face and forgive some very difficult realities about yourself, then the truth will not be withheld from you.
The act of setting out with the intent of being a stranger in a strange land is not new. On the contrary. The earliest scriptures indicates that Abraham used sacred journeying as a method to access revelation, as is witnessed in Genesis 12-1. Gen 12-1 states, “Leave your country, your family and your father’s house, for the land I [God] will show you. I will make you a great nation.” Abraham follows the call from God to perform actual setting out into the unknown, on pilgrimage, of sorts. Of course we know thousands of years later that it resulted in the founding information that guided the establishment of the three monotheistic traditions. There is an invisible hand that knows the ultimate potential behind all things and this benevolent hand is a guide that reveals.
P.S. I like Gilbert’s interpretation better :)
