The speaker walks us through the dark, assuring us that our eyes will adjust. It’s like stumbling outside into the night after being indoors; it can take awhile to be able to move confidently without falling over. Eventually, our eyes get used to the dark and we can stand up straight and face the road ahead. But, says the speaker, some darker nights, those of the mind, require a little more. The speaker says the bravest go forth in the darkness, sometimes walking into an obstacle like a tree. In the end, though, we make it to the road and are able to see our way.
