OOH! OWW!

(The title is a humorous twist on the rhyme scheme ;-)

Oh, Ow!

How sharp the share that plows

soul soil;

affliction tills in rows,

that I may plant

sweet seeds of hope

in heart new-softened now.

Another sower also knows

the power of the pain,

and whether I allow

or no, he casts in doubt 

which quickly grows.
