It's difficult for me to do it in my own home so what I was thinking about is finally staying a few nights in the hermitages at a nearby spirituality center. It's a very magical place run by a Christian denomination, but they're basically Druids - they specifically focus on nature-centered spirituality. Their hermitages are little one-room homes in the woods powered only by solar/thermal.
I didn't even know that was a thing? I usually just go camping for that sort of solitude and reset. But that's been getting harder to do lately, I wonder if there are any near me?
