The stunning [blow]!
What is a disaster?
What will make you realize something is going to stun [you]?
Someday mankind will act like scattered moths
and the mountains seem like tufts of yarn!
So anyone whose scales are weighted down
[will land] in pleasant living;
while whoever´s scales are light
will have a Pit to mother him.
What will make you realize what this will be like?
Scorching fire!
