The Buddha recommended 5 daily recollections, one of which is "I am of the nature to die. Death is unavoidable."
These Days of the Dead, preceded by All Hallow's Evening (Hallow E'en), are an excellent time to bring this remembrance to mind. Perhaps several times today and tomorrow.
All around us, people are sick and dying from COVID. Just like them, i am of the nature to become sick and die.
Our challenge is to have compassion for the suffering of others and for ourself. This is not a time to say, "Well, they were old anyway, so it doesn't really matter if they die." Put yourself in their shoes; put yourself in their bare feet. Walking on cold ground. Walking toward a grave. Put yourself in their bones. Put yourself in their skeleton.
