Here The Life Of Rivers Begins
They rise from the granite, sun themselves a little on the unsheltered plateau and drop through air to their valleys. Or they cut their way out under wreaths of snow, escaping in a tumult. Or hang in tangles of ice on the rock faces. One cannot know the rivers till one has seen them at their sources; but this journey to the sources is not to be undertaken lightly. One walks among elementals, and elementals are not governable. There are awakened also in oneself by the contact elementals that are as unpredictable as wind or snow.
