Opeth Easter Egg - Weird Laungage In the Track: "By the Pain I See In Others."

Some of you may have noticed at the end of the 6th track on Opeth's Deliverance album (The 6th track is titled: By the Pain I See In Others), there is a man speaking in an unintelligible language. Well, by performing certain procedures, this becomes intelligible. First, find an mp3 editing software, it can be a free trial, anything, as long as it can reverse music. Now, open up your editing software, and select the part where the weird speaking comes in. Reverse that part and listen. It is comprised of various parts from the song, Master's Apprentices. But, with just vocals, sung by Mikael Akerfeldt. This is the only egg I have come across in any of Opeth's work, and it is certainly an uncommon one.
