Joe originally wrote it on piano as a reflection of 9/11. Coming back to it on the Super Colossal record in 2006, he tried to write ten words for the title - based on the repeated ten note phrase (2:29-2:38) - but found that it was impossible to do, so he left it ambiguous.

Joe Satriani Tribute to 9/11: "Ten Words"
This was reportedly written on 09/12/01. We don't know what the words are. Joe Satriani has left them ambiguous. The music is great though!
