There is a message here about impermanence. While I've heard it many times before, somehow every time an unexpected event happens or I receive unwelcome news, I have to learn the lesson all over again. We are not in control of so many things.
Scared of death? Sure I am, I'm no hero and I'll probably fight against the dying of the light like anyone else. But ultimately, if I have an ultimately, I'm just damn glad I got to be here. And damn grateful to everyone (and I mean that in absolutely the widest sense) who made it possible.
According to the spiritual teachers I lean on, death doesn't exist. When we die, our soul leaves the physical body and reunites with our higher self. If we want to, and when we are ready, we can do another round.
