I know what it’s like to be an exile in your own home. I could shout with the Israelites from the Mountain of Curses: “This man will build his house, but never live in it.”
It’s one thing to talk about your home and your family objectively as the other and talk about it and conceptualize it and know that it’s good and what’s right about it and describe all the things that are good about the hearth and the home. But it’s another thing to actually live inside of it and experience it while knowing this and to, in the moment of living in it, know that you are there.
This is why it is so dangerous to be an exile in your own home: you are not actually there. A carcass of the undead might be sitting on the couch, but certainly not you.
It’s something King Cyrus probably knew about the exiled Jews in his kingdom. He was outside. He was an outsider. Far enough away from Jerusalem's temple to see and appreciate it. And one of the things he could appreciate was that people who cannot go home and be at home in their home, people who are desperate to be home, as all of us are, are unhealthy people who will eventually die of their sickness and infect everyone else’s home with their ghosts.
