It looks like Tibetan script, but oriented upside down in your image. The text starts with symbols shaped like this:
༄༅།, so orient the image in that direction so the those symbols are at the top. (Your second image has a nice close-up of this, but it should be at the top, not the bottom.)
However, Tibetan script is used to write several different languages and I can't read any of them, so I don't know specifically which language it is (Tibetan, Dzongkha, etc) or what the text says.
If no one who can read it sees your message here, you might try posting it in this thread:
