Umaswati, in chapter 8 of Tattvartha Sutra presents his sutras on how karma affects rebirths. He asserts that accumulated karma in life determines the length of life and realm of rebirth for each soul in each of four states – infernal beings, plants and animals, human beings and as gods. Further, states Umaswati, karma also affects the body, the shape, the characteristics as well as the status of the soul within the same species, such as Ucchi (upper) or Nicchi (lower) status. The accumulated and new karma are material particles, states Umaswati, which stick to the soul and these travel with the soul from one life to the next as bondage, where each ripens. Once ripened, the karmic particles fall off, states Umaswati.
