Dualistic faith means that there's this kind of interest in counterbalancing forces, for example, light versus dark, and of course, good versus evil, and one of the main ideas or words here are the ideas of asha and druj. So asha, these are the ideas of being principled, honest, ordered, and druj is the opposite. Druj is the idea of being unprincipled, dishonest, chaotic, and so there's a lot of talk and kind of insight or trying to get a better understanding of these dualistic natures in the world, and trying for humanity to be on the site of the good, the light, the ordered, the principled, the honest. Now, right over here is a key symbol of Zoroastrianism that you might see. It's called the farvahar. I'm probably mispronouncing it. Farvahar.
