Buddha categorized all beings in six kinds: of Heaven, of Humans, of Asuras, of Animals, of Ghosts and of Hell. (Six Realms: http://en.wikipedia.org/wiki/Six_realms
Buddha called all these beings collectively "The Great Assembly" and he explained that a being of any category may switch over to be other being of another category when reborn according to their deeds. That is the so-called "The Rotation of Six Categories of Being." (Samsara: http://en.wikipedia.org/wiki/Samsara_(Buddhism)
When someone reaches the state of not to be transferred to another category of being, he reaches the state of "Nirvana." (Nirvana: http://en.wikipedia.org/wiki/Nirvana
The four Chinese characters says "All Beings of the Six Categories" or, as Buddha, put it "The Great Assembly." (Rebirth: http://en.wikipedia.org/wiki/Rebirth_(Buddhist)
I hope that this may help.
