Arat Sabulungan is the local belief or religion of Mentawai community. The fundamental teaching of this religion emphasizes the harmonious relationship between humans, spirits, and nature. This religion believes that every single space and place is inhabited by the spirits. They are bound everywhere, so it is necessary to uphold good and ethical behavior in the surrounding nature. The corrupted acts against nature will disturb the peace of the spirits, which will in turn bring calamities and disruptions to the life. Viewed as the dwelling place of the spirits, the nature should be well kept through ecological ethics taught by Arat Sabulungan. In addition, since the nature is the center of this religious teaching, corrupting it means corrupting the body and the life itself.
