1 Zarathustra asked God: "O Lord, most beneficent Spirit, Maker of the material world, thou Holy One! How shall I cleanse the house? how the fire? how the water? how the earth? how the cow? how the tree? how the faithful man and the faithful woman? how the stars? how the moon? how the sun? how the boundless light? how all good things, made by God, the offspring of the holy principle?"

2 God answered: "Thou shalt chant the cleansing words, and the house shall be clean; clean shall be the fire, clean the water, clean the earth, clean the cow, clean the tree, clean the faithful man and the faithful woman, clean the stars, clean the moon, clean the sun, clean the boundless light, clean all good things, made by God, the offspring of the holy principle.

3 "So thou shalt say these fiend-smiting and most-healing words; thou shalt chant the Ahuna-Vairya five times: 'The will of the Lord is the law of holiness,' and so on.

"The Ahuna-Vairya preserves the person of man: 'The will of the Lord is the law of holiness,' and so on.

"'Whom hast thou placed to protect me, O Lord, while the hate of the fiend is grasping me?' and so on.

"'Who is he who will smite the fiend in order to maintain thy ordinances?' and so on.

"'Keep us from our hater, O Lord, and keep us in holy devotion!' and so on.

4 "If thou wantest to cleanse the house, say these words aloud: 'He is my greatest support as long as lasts this dreary world.'

"If thou wantest to cleanse the fire, say these words aloud: 'Thy light, first of all, do we approach with worship of Thee, O God!'

5 "If thou wantest to cleanse the water, say these words aloud: 'The waters, the signs of God, we honour: the waters in the tree, the waters in the stream, the waters in the rain.'

"If thou wantest to cleanse the earth, say these words aloud: 'For this earth we give thanks to God, this earth with the women, this earth which bears us, and those women who are Thy servants, O Lord!'

6 "If thou wantest to cleanse the cow, say these words aloud: 'For the cow we order thee to do these most excellent deeds, that she may have a resting place and fodder.'

"If thou wantest to cleanse the trees, say these words aloud: 'Through His holiness God made the plants grow up.'

7 "If thou wantest to cleanse the faithful man or the faithful woman, say these words aloud: 'May the beloved helper come hither, by God's leave, for the men and women of Zarathustra to rejoice, for the faithful to rejoice; with the desirable reward that is won by means of the law, and with that boon for holiness that is vouchsafed by the Lord!'

8 "Then thou shalt say these fiend-smiting and most-healing words. Thou shalt chant the Ahuna-Vairya eight times:

"'The will of the Lord is the law of holiness,' and so on.

"'Whom hast thou placed to protect me, O Lord?' and so on.

"'Who is he who will smite the fiend?' and so on.

"'Keep us from our hater, O Lord!' and so on.

9 "I drive away Aeshma, I drive away the Nasu, I drive away direct defilement, I drive away indirect defilement.

"I drive away Khru, I drive away Khruighni; I drive away Buidhi, I drive away Buidhitza; I drive away Kundi, I drive away Kundiza.

"I drive away the yellow Bushyasta, I drive away the long-handed Bushyasta; I drive away Muidhi, I drive away Kapasti.

"I drive away the Pairika that comes upon the fire, upon the water, upon the earth, upon the cow, upon the tree. I drive away the demon of uncleanness that comes upon the fire, upon the water, upon the earth, upon the cow, upon the tree.

10 "I drive thee away, O mischievous Satan, from the fire, from the water, from the earth, from the cow, from the tree, from the faithful man and from the faithful woman, from the stars, from the moon, from the sun, from the boundless light, from all good things, made by God, the offspring of the holy principle.

11 "Then thou shalt say these fiend-smiting and most-healing words; thou shalt chant four Ahuna-Vairyas:

"'The will of the Lord is the law of holiness,' and so on.

"'Whom hast thou placed to protect me?' and so on.

"'Who is he who will smite the fiend?' and so on.

"'Keep us from our hater, O Lord!' and so on.

12 "Away is Aeshma driven; away is the Nasu driven; away is direct defilement; away is indirect defilement driven.

"Away is Khru, away is Khruighni driven; away is Buidhi, away is Buidhitza driven; away is Kundi, away is Kundiza driven.

"Away is Bushyasta driven, the yellow; away is Bushyasta driven, the long-handed; away is Muidhi, away is Kapasti driven.

"Away is the Pairika driven that comes upon the fire, upon the water, upon the earth, upon the cow, upon the tree. Away is the demon of uncleanness driven that comes upon the fire, upon the water, upon the earth, upon the cow, upon the tree.

13 "Away art thou driven, O mischievous Satan, from the fire, from the water, from the earth, from the cow, from the tree, from the faithful man and from the faithful woman, from the stars, from the moon, from the sun, from the boundless light, from all good things, made by God, the offspring of the holy principle.

14 "Then thou shalt say these fiend-smiting and most-healing words; thou shalt chant 'Mazda ad moi' four times: 'O Lord, teach me excellent words and excellent works, that through the good thought and the holiness of him who offers Thee due praise, Thou mayest, O Lord, make the world thrive for ever and ever, at Thy will, under Thy sovereign rule.'

15 "I drive away Aeshma, I drive away the Nasu," and so on.

16 "I drive thee away, O mischievous Satan, from the fire, from the water," and so on.

17 "Then thou shalt say these fiend-smiting and most-healing words; thou shalt chant the Airyamaishya four times: 'May the beloved helper come hither!' and so on.

18 "Away is Aeshma driven; away is the Nasu driven," and so on.

19 "Away art thou driven, O mischievous Satan, from the fire, from the water," and so on.

20 "Then thou shalt say these fiend-smiting and most-healing words; thou shalt chant five Ahuna-Vairyas:

"'The will of the Lord is the law of holiness,' and so on.

"'Whom hast thou placed to protect me?' and so on.

"'Who is he who will smite the fiend?' and so on.

"'Keep us from our hater, O Lord, and keep us in holy devotion! Perish, O fiendish one! Perish, O brood of the fiend! Perish, O world of the fiend! Perish away, O fiend! Rush away, O fiend! Perish away, O fiend! Perish away to the regions of the north, never more to give unto death the living world of the holy spirit!'"
