SpiderJerusalem: No, not really- I took the terminology from an above poster, but I always pictured it as a playing-the-(acoustic, definitely)-guitar-in-the-Jerusalem-forest type. or the mountains by Tzfat. You know what I mean.
Chareidi means one who trembles (from Hashem). As long as we use this definition, this is probably what Moshiach will be like. As far as the societal grouping, I’m going to have to go with Yair Lapid on that one and admit that so many of these groupings are essentially modern in nature and thus i is very unlikely that one is the original.
