“But it was probably long before anyone thought of pottery that the river was first perceived as a metaphor of destiny, the "clan river" of eternity connecting the three worlds. The bear signaled--perhaps seemed even to oversee--the arrival of the salmon. The salmon were human food too, which made the first link in the man-bear-river-salmon system a tangible reality. We can only guess how the river's eternal flow, the upstream movement of the miraculous fish from the depths of a watery matrix toward the almost ethereal spring at the headwaters, or their fate in the stomach of the bear might have stimulated the concept of reincarnation. In time, the spiritual forces represented by the physical realities could be grappled with by a shaman, who would travel the river to the ancestral downstream and the immortal upstream in a trance instead of a boat.”
