I dreamed--oh blessed vision!-
that a fountain flowed
deep within my heart.
Tell me, water
By what secret channel
have you come to me
A spring of new life
I've never drunk before.
I found this poem in a book I'm reading by Barbara Sjoholm. This is her translation. I am sure I have heard this poem before. I remember those two lines and "oh blessed vision." Lovely. And when I looked Machado up on the Internet resources, I found a site with this poem in its entirety.
