Others taught me with having knelt at well-curbs <br /> Always wrong to the light, so never seeing <br /> Deeper down in the well than where the water <br /> Gives me back in a shining surface picture <br /> Me myself in the summer heaven godlike <br /> Looking out of a wreath of fern and cloud puffs. <br /> Once, when trying with chin against a well-curb, <br /> I discerned, as I thought, beyond the picture, <br /> Through the picture, a something white, uncertain, <br /> Something more of the depths--and then I lost it. <br /> Water came to rebuke the too clear water. <br /> One drop fell from a fern, and lo, a ripple <br /> Shook whatever it was lay there at bottom, <br /> Blurred it, blotted it out. What was that whiteness? <br /> <br /> Truth? A pebble of quartz? For once, then, something.<br /><br />Robert Frost<br /><br />http://www.poemhunter.com/poem/for-once-then-something-2/
