Gatha (Zoroaster) lyrics by Zoroaster
The Gathas () are 17 Avestan hymns traditionally believed to have been composed by the prophet Zarathushtra (Zoroaster). They form the core of the Zoroastrian liturgy (the Yasna). They are arranged in five different modes or metres.
The Avestan term gāθā (𐬔𐬁𐬚𐬁 "hymn", but also "mode, metre") is cognate with Sanskrit gāthā (गाथा), both from the Proto-Indo-Iranian word *gaHtʰáH, from the root *gaH- "to sing".
