The Tagakaulo tribe’s lifestyle is influenced by religious beliefs, ceremonies, and customs. They are touched by supernatural phenomena because they think ghosts are also part of the community. Their religious views represent their relationship with the divine realm, which has an impact on how they should act, behave, and interact with the unseen world. As a result, traditional belief systems and rituals have survived and continue to be practiced today. All aspects of our life are influenced by cultural belief systems and customs.
