Where our attention lies

I had a fissure  on my worn old thumb
The pain  was so severe my eyes both ran
I felt self pity, why is life so  cruel?
All day I  had grieved  like some old fool

Then I saw some  lights flash in my eye
Soon the sight  had  gone, I  quite blind
My eye,  its lids, its lashes full of blood
I had to  lie  face down upon my bed

Three months  passed then I had vision twice
The eyes  confused,  my mind seemed full of spite
Their experimental surgery  may help
Another person  back to normal health

The eye  stitched up, I thought about my thumb
Without perspective   we are quite undone
