the threads in her head

I'm suddenly quite stunned.

Maybe I should NOT have chosen literature.

Turning and turning in the widening gyre
The falcon cannot hear the falconer;
Things fall apart: the centre cannot hold;
Mere anarchy is loosed upon the world,
The blood-dimmed tide is loosed, and everywhere
The ceremony of innocence is drowned;
The best lack all conviction, while the worst
Are full of passionate intensity.

Surely some revelation is at hand;
Surely the Second Coming is at hand,
The Second Coming! Hardly are those words out
When a vast image out of Spiritus Mundi
Troubles my sight; somewhere in sands of the desert
A shape with lion body and the head of a man,
A gaze blank and pitiless as the sun,
Reel shadows of the indignant desert birds.
The darkness drops again; but now I know
That twenty centuries of stony sleep
Were vexed to nightmare by a rocking cradle,
And what rough beast, its hour come round at last,
Slouches towards Bethlehem to be born?

THE SECOND COMING
by W B Yeats

I read it halfway, and I'm lost.
