Mithra, commonly known as Mehr or Mithras among Romans, is an ancient Iranian deity of covenants, light, oath, justice, the sun, contracts, and friendship. In addition to being the divinity of contracts, Mithra is also a judicial figure, an all-seeing protector of Truth, and the guardian of cattle, the harvest, and the Waters.

Asha or arta is a Zoroastrian concept with a complex and highly nuanced range of meaning. It is commonly summarized in accord with its contextual implications of 'truth' and 'right', 'order' and 'right working'. It is of cardinal importance to Zoroastrian theology and doctrine. In the moral sphere, aṣ̌a/arta represents what has been called "the decisive confessional concept of Zoroastrianism". The opposite of Avestan aṣ̌a is 𐬛𐬭𐬎𐬘 druj, "deceit, falsehood".
