What does "玄晢中" mean?

[44raseac44]

I came across a few kanji that I don't understand when put together. I know 玄 is mysterious (I think) but what does "玄晢中" mean? I saw it on a talisman or sign.

It doesn't make sense as a Japanese word. 晢 is a variant of 晰, and it's rarely used. 玄晰中 doesn't make sense, either, though. It looks like a Chinese word or a Chinese name to me.
