[…] whateverreturns from oblivion returnsto find a voice: […] (18-20)
Shmoop thinks "oblivion" is even more disconcerting than buried consciousness. Seems like oblivion would dissolve our individual identities, deconstructing us, atom by atom. Yowza. How could we recover from that? Yet, somehow, we are reconstructed, transformed into our true selves. And you know it's really you because nobody but you has your voice.
from the center of my life came
a great fountain, deep blue
shadows on azure seawater. (21-23)
The fountain image triggers a rush of relief and joy. But where has this journey actually taken us? The fountain remains mysterious; we have to take it on faith that we've come to the right place. Notice the "deep blue shadows"? The words "deep" and "shadows" remind us of suffering, of "being buried in the dark earth." Yet those deep, dark experiences have been transformed into a radiant vision of azure seawater.
