Mara, often short for Mara-Papiyas, is the lord of the sixth heaven of the Desire Realm and the head of gods in Mount Meru. It is said that if a man could reach beyond the sixth heaven, he will then overcome all kinds of desires and delusions to go on the path to enlightenment. So there is only a line between the Buddha and the devil!
What the new angel meant to say about the "accident" :- "The previous angel got just a little stab through her heart nothing more, no need to worry about her."
