I thank the blog Gladsome Lights at http://gretchenjoanna.blogspot.com/ for the following George MacDonald poem. It's from A Book of Strife in the Form of The Diary of an Old Soul.
With every morn my life afresh must break
The crust of self, gathered about me fresh;
That thy wind-spirit may rush in and shake
The darkness out of me, and rend the mesh
The spider-devils spin out of the flesh—
Eager to net the soul before it wake,
That it may slumberous lie, and listen to the snake.
I've finally shaken off the melancholy of the last few weeks and stopped listening to the snake.
