Faravahar, believed to be a depiction of a Fravashi, as mentioned in the Yasna, Yashts and Vendidad
The Yashts (from yešti, "worship by praise") are a collection of 21 hymns, each dedicated to a particular divinity or divine concept. Three hymns of the Yasna liturgy that "worship by praise" are—in tradition—also nominally called yashts, but are not counted among the Yasht collection since the three are a part of the primary litury. The Yashts vary greatly in style, quality and extent. In their present form, they are all in prose but analysis suggests that they may at one time have been in verse.
