Third, concerning the length of lifespan: the Kośa-śāstra says that if the place of rebirth is not fixed in another place, one may take birth anywhere within this destiny. For instance, cattle have particularly frequent sexual activity in summer, dogs in autumn, bears in winter, horses in spring, while jackals and the like have sexual activity at no fixed time. If at that time this sentient being is to be born among cattle, but it is not summer, it is then born among jackals. If it is to be born among dogs, but it is not the season, it is then born among jackals.
