Perhaps this is a bit of plagiarism but sometimes it is fun to take various lines from an old poem and come up with a new poem.  Give it a try.  I took the first lines from each stanza of "WHY THIS LONGING" by Charles MacKay to make this one.

Why this longing, clay-clad spirit?
With the roar of wintry forests,
thou wouldst fathom Life and Being.
With thy feeble logic tracing,
be contented with thy freedom
clogged and bedded in the darkness.
Cease thy struggling, feeble spirit!
