sci-fi book where a meteorite gives 3 different kinds of telepathic powers to people who then vie for control

3 groups of telepaths each with different powers. They received their powers from a meteorite. One group is the strongest and are kind of in control. Another group wants to gain control. One group, I believe the strongest, have telepathic battles to determine the strength of one another conjuring up swords, walls, etc. in their minds. It was written by a lawyer. Could have been written in the ‘80s, or earlier.
