I suspect Indian subcontinent or Southeast Asia.
That looks very similar to the Tibetan prayer flags we’ve seen in Nepal.
it’s Tibetan.
seeing as it’s on a prayer flag it is probably repeating variations of “om mani padme om”. literally “om the jewel in the lotus”.
I don’t speak or read tibetan but from some knowledge of tibetan culture there’s a very high chance thats what it is.
Yes, see here. Contains this photo, which is very similar to yours.
It looks like Tibetan, if that helps narrow it down. I can’t translate it, though.
here’s a specific breakdown of the meaning of the “lungta” windhorse prayer flag you have.
Many thanks!
