Sometimes people will describe a moment or an overarching trend in their life as a "guiding light". Something or someone that illuminated their path, and led them through life. In my experience, though, that isn't quite right. Light illuminates but it blinds, too. We are literally not built to perceive direct sunlight, for instance. Between night and day, the starry sky is the more 'true' of the two, as well. After all, only a fraction of a fraction of our world is so brightly lit as to experience any day at all.
Darkness does not obscure. It is the absence of a thing. An empty void is passed through more freely than any other terrain, including by those things which grant us perception. And while it is true that to perceive anything, interaction is required-A fluid for echoes to shake, particles to interrupt the flying photon, a solid to press a finger against-the fallen tree in a deserted wood still rings in its death. Things are, even if we are not there to witness.
In the end, night isn't really better or worse than day. I plot these words on a screen, but they are justification for a preference that already possessed me. Still, I do not regret singing into the void.
