"The slametan (or selametan, slamatan, and selamatan) is the communal feast from Java, symbolizing the social unity of those participating in it. Clifford Geertz considered it the core ritual in Javanese religion, in particular the abangan variant. The feast is common among the closely related Javanese, Sundanese and Madurese people."
"The ceremony takes its name from the Javanese word slamet, from Arabic: salam, which refers to a peaceful state of equanimity, in which nothing will happen. This is what the host intends for both himself and his guests, by experiencing the egalitarian structure of the slametan and the petitions of supernatural protection from spirits."
