"Revitalization Movements

frequently begin after an individual receives direct messages from the spirit world telling him or her to convey divine teachings to the community. Referred to as prophets, such individuals become the conduits for communication between the spirit world and ordinary people. Essentially, the messages point out how people have become demoralized by straying from the right path and abandoning their traditional values and ethics. Although external forces may be causing people's suffering, the people themselves contribute to their troubles. The prophets teach that people must return to traditional ways, stressing the values of hospitality or civility, generosity, cooperativeness, and solidarity with relatives and community members. Leaders of revitalization movements proselytize others, always seeking to enlarge the community of followers and establish a network of believers."
