By Hearing Mass:
*  You are preserved from many dangers
& misfortunes which would otherwise
have befallen you.
*  You can diminish the temporal punishment
due to your sins
*  You shorten your purgatory by every 
mass you hear.
*  At the hour of death, the masses you
have heard will be your greatest consolation.
*  Every mass will go with you to judgement 
& plead for pardon.
*  One mass heard by you during life will be 
of more benefit to you than many heard 
For you after death.
*  You win for yourself a higher degree of
glory in heaven..
