Navachristianity
According to the Legends of Dune trilogy, Navachristianity is the religion of the ruling class on Poritrin. However, according to Dune it is found on the planet Chusuk, but there is no explanation of its tenets. Three tenable etymologies have been suggested. One treats it as a portmanteau of Navajo with Christianity and assumes Herbert was alluding to a movement comparable with the Native American Church; the other treats it as a worn down fusion of Nauvoo with Christianity in reference to the American religious movements begun there. The third derives "nava-" from 'new' in Sanskrit, the liturgical language of Hinduism and Mahayana Buddhism, often being used in the same sense as 'neo'. Thus, Navachristianity may simply mean 'neo-Christianity', or represent a blend of Christian philosophy with Indian religion.
