I just did a search of the Indology archives for the terms śāntamūrti and śāntimūrti, however, the search produced no results. I thought perhaps I might come across this term in the Śānti Parva, although a quick search came up also with no results.

I'm wondering if anyone has come across such a term in reference to 'embodiers of quietude' in any text, and if so, could you please inform me of this particular text. 

Thank you.
