The "soul" or spirit of a person has two dimensions; (1) human body and (2) spiritual. Soul referred to as kaluluwa by the Tagalogs or Dungan by the Ilonggos comes from the root word duwa, two. The Dungan is not seen by the human eye, it takes on a different form. For importance, it can be in a form an insect or a small animal such as lizard. The Bisayans believe that the Dungan leaves the body while the person is asleep. Travelling Dungan outside the body must be free from accidents such as getting trapped in a jar. Only when the soul has safely reunited with the body, the person will be awake. Dungan is also connoted as "willpower". If a person has a strong willpower, is it said to have a strong Dungan.
