There are numerous paths of entry – window, vent, black hole, shadow. There is symmetry, there is not symmetry. Mystery text attempts to give a hint as to what is going on, but it is indecipherable, letting us know that there is meaning but we are not privy to that meaning. So we stand outside, wondering.
This image was printed on cheap watercolor paper with homemade AZO silver gelatin emulsion, and is part of the Braddock Equivalents project.
Meanderings, at best 
There are paths of entry, yet they’re blocked – the windows barred, the text, as you said, indecipherable. I get a strong feeling of being kept out in this very evocative photo. And I think it’s so cool that you’re making your own silver gelatin emulsion!
