Handbook for Explorers 2

Poised upon this vantage point or that, you
Can expect to see only to the edge
Of what you count as true. And there, an age
Away, breaks a sea, where it seems a new
World starts, or if not new, where old stories
Cease to be in charge, and every certainty
Drowns in the moving water and the sky
Rises downwards, fades, and past thoughts freeze.
Yet, don't think the case is closed: what happens
Next is full of wonder, and what you'll find
May seem to have no use, yet shines and runs
Like water in the gullies of the mind,
Once dry and untenanted like the moon's
Seas, now potent as a new book opened.
