The mirror shows a perosn but who 

I do not know,

I can see the outside features, but

the heart doesnt show

Who could be staring at me, an

angle, saint, or beast?

Without a greater knowledege, it's

hard to tell the least

It only shows the person, but not

who we really are

It might show me coal, when I'm looking

at a star

The mirror is good for looking, but 

only from outside

It only shows the surface, and

that's not how we are defined
