Si-Dyoni derives from ‘Si’ ('Earth'), and ‘Dyoni’ ('Sun'), which follows the cult of animism and ritualistic nature worshiping in the form of spiritual deities where particular kind of animals or chickens are sacrificed at the altar (yogging-made out of the bamboos and wooden leaves with particular leaves or vines in stuffed shape) to please the spirits, more likely not anger them and keep them in their kind form.

Priest or Nyibu shaman who are born with their powers are the ones who communicate and negotiate between the other world.

The TWS or TCS also have many subgroups, and have been helping in shaping the future of the state.
