The Japanese Word, Mu

Yes, sometimes there are no clear answers to a question. While going undergoing a training in palliative care counselling, i was told there will be a question frequently asked , "Why me " ? And the answer to it would generally be "I dont know ". But in order to nudge the questioner go deeper , we need to help him to explore his inner in a deeper way and answer the question himself by keeping on the conversation which may lead to the answering of the question by himself .
