Read it through once

And yet--she has not spoke so long! What if heaven be that, fair and strong At life’s best, with our eyes upturned Whither life’s flower is first discerned, We, fixed so, ever should so abide? What if we still ride on, we two, With life forever old yet new, Changed not in kind but in degree, The instant made eternity,-- And heaven just prove that I and she Ride, ride together, forever ride?
