Another form of dualism is the belief in two opposing, equally balanced gods or pantheons of gods. Generally one god/pantheon represents good, or sometimes order, and one represents evil, or sometimes chaos.

A classic example of a dualistic religion would be Zoroastrianism, which holds that there is a good of good, Ahura Mazda, and a god of evil, Angra Mainyu. The two are equally balanced and eternally in conflict.
