Life in a Candleholder

We all give off light;
Neither the intensity 
	nor its brightness is measures
Rather, how far it reaches darkness
For a simple spark is complex
	it may mean there’s a way out
		or maybe there’s none

After all, its vulnerability conquers all
It is just a flicker of light
The candlestick makes it all happen
But the holder it stands upon
	makes it all work well
