Many Avestan texts are considered to have a great protective capacity against the daēuuas, especially the names of the Amәѕa Spәta, their Yašts and the Staota Yesniia (above all the Ahuna Vairiia). They are combined in different forms to provide bāǰ „prayers that accompany the ritual action“ and keep the daēuuas away from the ritual. Most ritual actions are accompanied by three bāǰ: one opening, one closing and one accompanying bāǰ. The use of such bāǰ is especially frequent in the purification rituals. V10 and 11 are examined under this perspective and it is concluded that V10 presents probably the alternative accompanying bāǰ for a baršnum-ceremony and V11 for a purification ritual for different elements.
