But Jasper's power worked on the physical part of the body. Supposedly Jasper's power adjust hormones and endorphins (blah, blah)....things that truly affect the body. That's how Jasper controls emotions...he does it by physically readjusting a person's body chemistry. But MOST other vampire's powers affect the mind. That's why so many gifted vampires could never affect Bella. Bella was a mental shield...any vampire's powers that affected the mind would not work on her. However, it a vampire's powers affected somebody physically...then Bella would feel it...and she wouldn't be able to shield anyone either.
