My oldest of enemies,
Thought processing fiend,
So full of ways to undermine me.
True culprit of my woes,
You answer to me, yet to no one at all.
I know what you are, yet
I truly do not.
To know your true face,
May I dive beneath the waves of sanity?
Shall I waltz to your ever discordant tunes?
Or will you forever elude me?
If time may prove just one thing;
I'll evermore stand against you, until I win.
Another of my puzzle poems. I've actually had the hidden sentence and solution to this one written down long before I wrote the poem itself, I just wasn't sure what to do with it. Some realizations brought to light by recent events, however, made it clear what it was for.
