I'm trying to read every religious text I can find to try and have more of a debate against people of that religion. The one I can't seem to find is the Avesta. It is the text for Zoroastrianism. Can anyone help?

In theory, I like Zoroastrians. They believe that they don't have to force their religion down your throat.

Whats the non tl;dr version of the Zoroastrians religion?

Deepest I ever dig is wiki.
