A submarine sinks down to the bottom of the darkest depth, but it is not sunk.
It will overcome the trench, bringing with it, articles from the bottom that we would like to examine further.
Articles from the darkest place, a place that no light has ever touched.
Be like the submarine.
Go to the dark place, all the while protected from the intense pressure.
But also, be like the submarine, do not be overcome by the dark and return to the surface with perspective.
