When day turns to night, the darkness isn't all-consuming. Light found from any source complements and balances the dark.
If you aren't looking for the light in the dark, the light may never be found.
Just because the environment rejects light doesn't mean you can't have it.
Light is a shield against overpowering darkness, just as shadow is a shield against overpowering light.
The light doesn't always show you where you're going...
...but it can show you where you are.
Make your own fire. You only need a spark; you have the rest.
When you understand the light as well as the dark, you can shape both together to work for you. Find the balance, and you'll find yourself.
