Don't eat too much of the food
That becomes a curtain over your eyes.
If you do, you won't be able to find your way back home.
Although you think your life
Depends on this little morsel of food,
It's actually more like a hair
That has grown too long
And is covering over the eyes of your soul,
A curtain covering over your head's eye.
