Words can be precious. Especially when they're sealed inside a hanging reliquary. As soon as I saw the rolled up text inside the taxi, I wanted to know what it said. Was it an ancient prayer, or perhaps some kind of old, sacred document? The writing appears to be Chinese, rather than Thai or Sanskrit, but I didn't ask the driver about it because it seems like something personal. If the taxi driver wanted me to know what it said, he would have hung it up on the ceiling with an English translation.
