What's going on with the Dahn Yoga place?

[philipph.livejournal.com]

I noticed the past few days (maybe all week?) the "Dahn Yoga and Healing" (or whatever it's called) location has had a giant "Space Available" sign in the window, and I haven't seen anyone inside.
I may just have been going past at different times from usual, but in the past it's felt like there's someone in there all the time.
Looks almost abandoned now.
Does anyone know what happened, if anything?
Not complaining, or anything. I've never been there, so in principle I wouldn't miss it if it disappeared. And I gather there's a creepy cult-ish vibe about it in general (though my understanding is that some locations are far creepier than others).
