Too long a sacrifice Can make a stone of the heart. Oh, when may it suffice? - William Butler Yeats

To long a sacrifice can make a stone of a heart

Too long a sacrifice
Can make a stone of the heart.

Too long a sacrifice
Can make a stone of the heart.

Edain came out of Midhir's hill, and lay
Beside young Aengus in his tower of glass,
Where time is drowned in odour-laden winds
And Druid moons, and murmuring of boughs,
And sleepy boughs, and boughs where apples made
Of opal and ruhy and pale chrysolite
Awake unsleeping fires; and wove seven strings,
Sweet with all music, out of his long hair,
Because her hands had been made wild by love.
When Midhir's wife had changed her to a fly,
He made a harp with Druid apple-wood
That she among her winds might know he wept;
And from that hour he has watched over none
But faithful lovers.

One often hears of a horse that shivers with terror, or a dog that howls at something a man's eyes cannot see, and men who live primitive lives where instinct does the work of reason are fully conscious of many things that we cannot perceive at all. As life becomes more orderly, more deliberate, the supernatural world sinks farther away.
