 So as not to disturb these spirits, the caves were avoided, no animals were herded there and no wood cut or twigs broken.Once a year the Sandawe would go to the caves to perform rituals of sacrifice in order to make sure the spirits would not be spiteful and interfere with the community's general well-being.People would go to the caves in the hills as a group shouting prayers to the spirits, assuring them that no one had come to disturb them, but had come to pay their respects.
