Take this kiss upon the brow!
And, in parting from you now,
Thus much let me avow

Of a surf-tormented shore,
And I hold within my hand
Grains of the golden sand
How few! yet how they creep
Through my fingers to the deep,
While I weep – while I weep!
O God! can I not grasp
Them with a tighter clasp?
O God! can I not save
One from the pitiless wave?
Is all that we see or seem
But a dream within a dream? by Edgar Allan Poe
