I am curious about that symbol. Here's a bit closer look:
I haven't been able to suss out that design. It looks like Sanskrit to me, but it isn;t one of the chakra symbols, and I can't find anything else that matches. Using this website, the closest hots are small ligature Armenian alphabet symbols, but again, I can't find a precise match.
I even tried flipping the symbol over, which looks even less natural to me, and it still didn't get me anywhere. The designs on the didn-t help much either:
I see a building, and maybe a torch or some pliers or pincers below it
The other side has another building, or maybe a book or a box, and the same tool or object.
Any guesses out there -- or even better, real knowledge?
