There are various kinds of puras, which are allotted for different ritual activities.We have noted the Pura Dalem, which is associated with death rituals. This is also used for worshiping Shiva (often connected with cremation grounds); the actual cremation is performed elsewere.Another example of a pura is the Pura Tirta, or water temple. It is connected to the irrigation system. From this temple priests physically control the flow of irrigation water to the rice fields, and perform rituals to ensure the water’s purity. Temples are commonly built at places in Bali where water passes, since these places have ecological, economical, social, and of course spiritual importance.The Pura Desa in a village is dedicated to the worship of Brahma, and of course entails various ritual activities.
