Kind of not really though:
"So yes, technically the lyrics originated in an old Welsh poem about an army of mobile trees. However, the poem has gone through quite a journey to get here. A broad translation into English, a sketchy pseudo-translation into Sanskrit, and then even further modifications to make the words more pronouncable and aesthetic, as well as robbing it of what little original meaning still remained. So basically, it doesn't really mean anything except for a lot of the word "dreadful", but it's interesting to think about where the words came from."
