Márgarét, áre you gríeving
Over Goldengrove unleaving?
Leáves, like the things of man, you
With your fresh thoughts care for, can you?
Áh! ás the heart grows older
It will come to such sights colder
By and by, nor spare a sigh
Though worlds of wanwood leafmeal lie;
And yet you wíll weep and know why.
Now no matter, child, the name:
Sórrow's spríngs áre the same.
Nor mouth had, no nor mind, expressed
What heart heard of, ghost guessed:
It is the blight man was born for,
It is Margaret you mourn for.
This suggests that our souls or spirits or subconscious minds know more than we would consciously admit to ourselves. 
 There is a gentle rhythmic effect of the two balanced clauses in this line, aided by the  alliterative  “h"s in "heart heard” and “g"s in "ghost guessed”. This line is a good example of Hopkins' sprung rhythm.
