GĀTHĀS, part 5:

VAHISHTOIST GĀTHĀ

YASNA LIII

I The best prayer has been answered, the prayer that I, Zarathustra uttered : that Ahura Mazda might grant those boons that I and every Ashavan most wished for ; those which follow from living according to the Good Order : even a life that is prospered for eternal duration [Joyful Eternal Life].

II By these Laws of the Faith which I have proclaimed, you may obtain that life of the Good Mind : on Earth already, as well as in Heaven later !

III And to both of you , bride and groom [man and woman], I say : let each one respect and love each other, in Holy Order ;  thus alone shall the home-life be happy to each of you !

 IV O Mazda ! You possess that Power which, in the End, will banish and conquer all evil ; and Yours is the Kingdom of Eternal Life, by which You bestow the highest of Blessings [Eternal Life, Ameretat] on every Ashavan who will lead his life in the right way [according to ASHA]
