Mentawai also have very strong belief towards objects they think are holy. The people are characterized by their heavy spirituality, body art and their tendency to sharpen their teeth, a practice they feel makes one beautiful. Mentawai tend to live in unison and peace with the nature around them because they believe that all things in nature have some kind of spiritual essence.
