The interiority of this reminds me of two lines in one of Rilke's poems in French, which he talks about the center of a rose: "C'est ton interieur qui sans cesse / se caresse, dirait-on." ("It's your interior that ceaselessly embraces itself, one might say.")
Okay, on second thought, maybe it's not actually as relevant as I thought. But Morten Lauridsen's musical setting of that poem
came bubbling up in my mind, anyway.
I love the way you've handled the last two lines in particular. Very nice.
I would prefer to see this titled "Buddha in the Mandorla," since that image explains so much in the poem that follows. "Buddha in Glory" is too vague and requires a note, I think.
