Rammstein

I found that Reise, Reise, Rammstein's instrumental metal band, did a fine job portraying the music in his piece, Dalai Lama. It is interesting that Reise, Reise means Arise, Arise in one German translation, but it means travel or journey in another form. Ironically, I have noticed that in other pieces by Rammstein, he tends to use double meanings. I also found that his lyrics are rarely simple and cannot always be perfectly translated. It seems like there are always double meanings in his pieces, so I wonder what inspires him to do this? I just found this very interesting and clever of him and didn't know if anyone else had anything to add or had any explanations that I may have glanced over or forgot about.
