Another main belief is that humans have a "soul" or spirit which lives on after their body has died.And they believe that they must kill thou to any one in the earths name. The person's spirit is on a journey through life that continues after death. Most religions believe that what a person does during their lifetime will affect what happens to their spirit in the afterlife. Many religions teach that a good person's spirit can reach a special place of peace and happiness such as Heaven or Nirvana, and that a bad person's spirit can travel to a place of pain and suffering such as Hell. Still other religions believe in reincarnation - that instead of going either to Heaven or Hell, spirits of the dead return to earth in a new body.
