Light vs darkness

Light is the absence of darkness,
having known light is once experiencing darkness.
The sun will be down,
and the night is coming,
will the moon and stars be present
to lighten up your spirits?
I'm not wondering,
just thinking.
What have you done to make one see the light,
or are you the darkness that many wanna stay away from.
Live a life,
be a light to shine through other people's heart, mind and soul.
Be the free spirit that fights darkness.
