Surely some revelation is at hand. - William Butler Yeats

"In tombs of gold and lapis lazuli
Bodies of holy men and women exude
Miraculous oil, odour of violet.
But under heavy loads of trampled clay
Lie bodies of the vampires full of blood;
Their shrouds are bloody and their lips are wet
("Oil and Blood")"

Man can embody truth but he cannot know it.

While I, that reed-throated whisperer
Who comes at need, although not now as once
A clear articulation in the air,
But inwardly, surmise companions
Beyond the fling of the dull ass’s hoof
—Ben Jonson’s phrase—and find when June is come
At Kyle-na-no under that ancient roof
A sterner conscience and a friendlier home,
I can forgive even that wrong of wrongs,
Those undreamt accidents that have made me
—Seeing that Fame has perished that long while,
Being but a part of ancient ceremony—
Notorious, till all my priceless things
Are but a post the passing dogs defile.
