A deep but dazzling darkness.

I heard these words some years ago and did not know who wrote them.Henry Vaughn was a 17th Century metaphysical poet and mystic.The quotation seems to imply a paradox as darkness is not dazzling..but I think that’s because we cannot  capture God in discursive language as if He were an object in our world

There is in God (some say) a deep but dazzling darkness.”
― Henry Vaughan
