Most people, sometime in their life, enter into a period of seeking. The language they use to describe their quest may be different, but the intention is the same -- to tap into a higher dimension of knowing and become self-realized.
Here's a story you can probably relate to: You are walking down a street when a friend, coming the other way, stops, looks you in the eye, and asks "Whassup?" It's a question you've heard a thousand times before -- the default, open-ended salutation.
During the shows an announcer explains that the walkers are Sawau tribesmen from Beqa, and that their skill is handed down from generation to generation. How all this came about, he says, is told in an ancient legend.
