Ashem Vohu

The Ashem Vohu (/ˈʌʃɛm ˈvɔːhuː/, Avestan: 𐬀𐬴𐬆𐬨 𐬬𐬊𐬵𐬏 aṣ̌əm vohū) is the second most important mantra, and one of the most important prayers in Zoroastrianism. It is dedicated to Asha, a Zoroastrian concept denoting truth, order or righteousness.

Together with the Ahuna Vairya, the Yenghe hatam, and the Airyaman ishya; the Ashem vohu forms the four mantras that enclose the Gathas in the Yasna. It is also at the end of most of the prayers in the Khordeh Avesta, except a certain few, most notably the Fravarane.
