Sorry, coming from a Zen Buddhist perspective, I just fell out of my chair laughing at that one line
I just picture someone holding a stick, whacking people and seeing an instant aura of enlightenment come over them. How easy life would be if that existed!!!
But anyway, yeah, something like that doesn't exist. I've found that those who need to listen to a message like the one the OP mentioned, are always going to be the ones turning a deaf ear.
If a conflict is of a personality difference in nature that escalates to a full scale conflict, you might as well beat your head against a brick wall until your skull splits open and call it mediation. They need to be willing to listen in order to mediate anyone and at that point, usually their ears turn off.
