the word "shanthara" related to which religion?
I googled it. I got a redirect to Zaratustra, but you are correct, shanthara is hot air. It does not appear in any Christian, Jewish, Muslim, or Hindu database. However, it is a foregone conclusuion that Physicalist will create yet another fraudulent screen name to make it sound like it existed.
Such is the deviancy of deranged and fanatical cultists.
I have never heard the term, although a small and localized Hindu group could have coined the word. India has over 60 languages and 300 dialects in its vast terrain. The most popular language in India is American English.
