The flute sings of an ancient riverbead one hundred fathoms deep, far below the Potaro River that runs to the Waterfall. Two rivers then. The visible Potaro runs to the Waterfall. The invisible stream of the river of the dead runs far below, far under our knees. The flute tells of the passage of the drowned river of the dead and the river of the living are one quantum stream possessed of four banks.
