Here's a poem from Rilke:
I love you more than all the fires
that fence in the world,
for the fire makes
a circle of light for everyone,
and then no one outside learns of you.
But the darkness pulls in everything;
shapes and fires, animals and myself,
how easily it gathers them!—
powers and people—
and it is possible a great energy
is moving near me.
I have faith in nights."
- Rainer Maria Rilke, On Darkness
