So I'm trying of think of something monastery like, but without the religious aspect, and I'm really drawing a blank. Since you basically surrender your life to the community and ultimately to whoever is leading it, the religious element seems almost necessary to make this work. I think the only exceptions to this are probably something like the military or meditation/yoga practice communities - but they almost inevitably come with religious elements to them(although in some you can be much more lax about actually subscribing to the spiritual elements).
