In traditional Buddhist countries one is encouraged to reflect on death. I think it is a very important reflection. Otherwise we forget about the most certain thing in life and we assume that we are going to live forever. So when you encounter death it can really give you a shock, you will be taken by surprise.
There are some interesting stories about people who have been able to laugh at life, and they were able to laugh at death in the same way. At present I am reading a book about how people met their death. It is fascinating how many of them have been able to really laugh at death and dying. There is a Zen story that comes to my mind, about a meditation master who was dying. When he realised he was dying he called all his students and asked them: “In what posture have you seen people dying?” His students replied: “In so many different postures.” The Zen master continued: “I am going to die in a most unusual posture.” After that he stood on his head and then he died! It shows that one can be playful about life and even about death.
