WISDOM

Din, or Daena, is religious insight: knowledge and wisdom in spiritual matters.

I We sacrifice to the most right Ahura of Wisdom, who was made by Mazda, and so is Holy. II We sacrifice to the good Law of the worshippers of Mazda, to whom Zarathustra did sacrifice for the Wisdom of Thought, the Wisdom of Speech, and the Wisdom of Deed. 

III And also for this boon : that the most right Ahura of Wisdom, who was made by Mazda and is Holy, would give him the swiftness of foot, quick hearing of the ears, strength of the arms, the health of the whole body, and the eye-sight of the eagle ; that He, (the Holy Zarathustra) might think according to the Law, speak according to the Law, and do according to the Law !

IV I bless the sacrifice and prayer, the strength and vigor of the most right Knowledge, which was made by Mazda and so is Holy, and of the good Law of the worshippers of Mazda !
