Worry
If your soul is lying in the grass in a treasure chest, you're going to worry about it. It's just sitting there, out in the open, waiting for anyone to come and open it.
Picture your soul curled up inside this treasure chest that's just sitting out on the grass. Anyone could open it up and look inside, and this worries you quite a bit!

None
Unfortunately, you also worry about opening it yourself. You stand in front of the chest and think, "Should I open it? Nah, yah (なや). Wait. Nah. Yah. Dang, you can't make up your mind.
You worry about what you'll find if you look directly at your soul. But you also worry about what will happen if someone else looks. So you're stuck in a constant state of worrying: nah or yah?!
