In nature you get death and life co-existing together. They are not separate. They are inter-related, inter-connected. This is how we should see life and death. Not to see them as separate but to see how they are connected, inter-related. Then ideally, whether you live or die it makes no difference. Then you know the way to live and you know the way to die.
Death is the most certain thing in life, and what is unfortunate is that we forget the most certain thing in life and get involved in other things that are uncertain. But if you can be with this most certain thing in life, then when we encounter it, either in ourselves or in others it doesn’t affect us in the same way.
In Buddhist meditation this reflection on death plays a very important role in the practice. In Sri Lanka, in forest meditation centres, when you visit such places you see skeletons being used by meditating monks to remind them of the fact of impermanence and the fact of death.
