When a vision of death is real, we start seeing everything in its proper place and perspective.
Imagine that a doctor tells you that you have cancer and your time is very limited.
What would you do? What plans would you make? How would you start behaving?
If the answers include, for example, traveling, enjoying each moment with your family, making peace with your enemy, etc., then maybe it would be good to not wait for such bad news from your doctor to start acting in this right way now.
