Spirits of light

I see a shadow, a figure of sorts
drifting to and fro, out the corner of my eye,
I feel its energy, anger and dispair
it grips me and comsumes me.

Just when I can't take it any longer,
the energy changes, now serene and peaceful
and I ask myself, " how can this be"?
two entities in one, how deceiving is that?

The answer came to me in muffled whispers,
"You know the answer", you feel the shivers,
as you realize the truth behind those voices
"There are two sides to every coin'!

Even an entity has two faces, " Good and Evil".
