There is a misty twilight of the soul,
A sickly eclipse, low brooding o'er a man,
When the poor brain is as an empty bowl,
And the thought-spirit, weariful and wan,
Turning from that which yet it loves the best,
Sinks moveless, with life-poverty opprest:—
Watch then, O Lord, thy feebly glimmering coal.
George MacDonald, The Diary of an Old Soul (February 25).
