You kind of imagine this idea that good thoughts lead to good words, and that combined they can lead to good actions. And on the tail here, and these are the things you should avoid, these are the bad thoughts, the bad actions, or the bad thoughts, the bad words, and the bad actions. Along lines this idea of dualism, especially the fascination with the ideas of light, fire is a very important element of the Zoroastrian faith. In fact, if you visit a Zoroastrian temple, you will see an eternal fire, and they feed that fire five times a day. Another very important element of the faith is water. And the sacred text for the Zoroastrians is called the Avesta. And the Avesta is written in a language called Avestan, and it's called Avestan because it's the language that the Avesta was written in, but it's written in a language that is closely related to ancient Sanskrit.
