Death is definitely an important concept for a person realise, process, understand and accept if you want to be at peace with Life.
Death would have a different meaning to everyone, some will be right some will be wrong, but at least everyone who accepts it in their own way will be at peace.
The hardest thing of all is to find a black cat in a dark room, especially if there is no cat.
