Hidden Evil

I looked where many flowers grew, and I said:
"The way I walk is barren, yea, and long;
Surely one hour of rest can do no wrong."
And so 'mid thickest of the grass I laid
My limbs; the blossoms met above my head,
And as I lay, half-eased, I heard a song.
Which seemed to me a psalm, and then among
The flowers, with a faint halo round her shed.

Came singing a fair woman with drooped eyes.
Oh, perfect soul, she touched me where I lay;
She softened all my life's sad memories;
But even while she soothed me with her sighs,
A fiend possessed me, that I might not stay:
Her breast I bruised, then turned, and went my way.
