Dragon Ball Super fans have come up with a theory about Jiren and his seemingly unlimited power, and it might very well reveal how the Tournament of Power will progress in future episodes. The two DBS fans shared quite an interesting theory in a subreddit dedicated to the show.
According to Reddit users Hydrox2016 and BetterGoHam, Jiren might have reached a Buddha-like state, which is why he defeated Goku with little effort. Hydrox2016 linked his theory to the Chinese legend, Journey To The West — an ancient tale telling the story of the Monkey King.
Most fans of the series will know that Akira Toriyama used Journey to the West as a source of inspiration for Dragon Ball. Goku, in particular, is loosely based off the Monkey King from the ancient story. Hardcore Dragon Ball fans will remember that Goku was originally dubbed the Monkey King in the classic DB manga and anime. The Saiyan even had a tail to go with it.
