I recently rented this movie named "Into Great Silence". It's about some Carthusian Monks in Switzerland (if I remember correctly) who take a life-long vow of silence. Not a documentary as such, it follows the monks through a period of about a year. It's quite long, over 2 hours but I found it to be such an experience of just being here now. It's also not heavy-handed "religious". I must admit to be a bit wary of that but it was recommended in a Buddhist review so I figured, "What the heck".
Has anyone else viewed it and if so, what do you think?
