What does "life sustains tragedy" mean?

It seems like "life helps us escape of the effects of tragedy" or i could also read it as "life provides us with all the things needed for tragedy"

I'm a littttle confused about which (if any) it is

Out of context, it's hard to tell.

Do you see it as referring to how a person continues to find meaning in life after a tragedy (perhaps the death of a loved one)?
