 Composer Don Davis (I) (qv) thought it would be wasteful for the  choir to be singing simple "ooohs" and "aaahs" during the climactic  battle cue, "Neodämmerung". He asked that the Wachowski Brothers  (Andy Wachowski (qv) and Larry Wachowski (qv)) bring him some  sort of text appropriate to the movie, which the choir would sing.  They returned with extracts from the Upanisads which reflect the  themes of the trilogy. The full lyrics of Neodämmerung are available  on Daviss website.
