The Drop, that wrestles in the Sea — Stage Setting

The Drop, that wrestles in the Sea-1
Forgets her own locality-
As I-toward Thee-

She knows herself an incense small-4
Yet small-she sighs-if All-is All-
How larger-be?

The Ocean-smiles-at her Conceit-7
But she, forgetting Amphitrite-
Pleads-"Me"?
(F.255/J.284)
