Two stars may look, for us, like they have about the same brightness, but it may be that one is a hundred times farther away... and 10,000 times brighter. The two things cancel out in this example. The "absolute brightness" tells us how bright a star or other object REALLY is. It is defined as how bright the object looks at a standard distance.
