I've been to Graceland a couple of times, and even wrote a little gift book about Elvis for a book packager years ago. The following passage, though, which comes from Darcey Steinke's memoir, Easter Everywhere, strikes me as about the truest thing I've ever read about E.P.
In Graceland light seems to come at you from all directions, as if the sun has liquefied and flowed into the floor, walls, and ceiling. I recognized in the glittery decor a longing for transcendence that is often labeled as tacky.
"A longing for transcendence." Beautiful.
