All right - I will post this in this thread, since it's sort of related.
So I did indeed find my way out of the Meditation Room (by the way that room is brutal with the "guests" that come into that room!)
Had to run and hide more than once (which is why I think that particular hall and escape appears, for that very reason!)
At any rate, found my way out of the Meditation Room, and eventually explored the western side and found the Healing Crystal. And nowhere else to go around here. But I know this can't be the entire map. There is a small pit, that's open next to the crystal, so I thought I'd jump down. But there is no escape out of the room when you jump down into the pit. No buttons that I could see. No hidden walls that I could find. You would literally just live forever down there.
I will share my two maps... (two map images within spoiler tags)...
Before I go down the pit, it looks like this:
Once I fall down the pit, the map changes back to the other configuration...
