Three stanzas, three pleas to unleashed nature: to the giant waves that break roaring, to the hurricane that snatches the dry leaves, to the storm clouds that wrap the lightning. Of all three he asks the same thing: «carry me with you!».
And in the last line, after so much fury, the reason appears, said almost under his breath: he wants the tempest to carry him off «out of pity», because he is afraid of being left «alone with my grief». It is Bécquer's Romanticism at its purest: to beg the immense to tear him out of himself.
The verse is kept in Spanish. Translating it in passing would replace the work with a paraphrase of it.
