The Tenggerese also worship a host of spirits (ancestor worship). They include cikal bakal, the spirits of the founders of the village, the roh bahurekso, the village guardian spirits and the roh leluhur, the spirits of the ancestors. Rituals to propitiate these spirits are conducted by special priests. During these rites little doll-like figures representing the spirits are clothed in batik cloth and are presented with food and drink. It is believed that the spirits partake of the essence of these offerings. The Bromo volcano is considered one of the most sacred places. If it erupts, they believe that their god is very angry.
