Ameretat
aka: Amurdad

Ameretat means "Deathlessness and Immortally". Together with Haurvatat, it is the ultimate goal and represents the completion of our evolutionary development and the final achievement of our life on earth. She is associated with plants. She personifies immortality and rules the physical and spiritual aspects of eternal life as are symbolized in plants. Ameretat is the Amesha
Spenta of long life on earth and perpetuality in the hereafter. In the day-name and month-name dedications of the Zoroastrian calendar, the seventh day of the month and fifth month of the year are named after Ameretat/Amurdad/Mordad and are under her protection. Her eternal opponent is the Arch-Demon of aging, Zarich.

The word amərətāt is grammatically feminine and the divinity Ameretat is a female entity. Etymologically, Avestan amərətāt derives from an Indo-Iranian root and is linguistically related to Vedic Sanskrit amṛtatva. In Sassanid Era Zoroastrian tradition, Ameretat appears as Middle Persian Amurdad, continuing in New Persian as Mordad or Amordad.

The relationship between Ameretat and Haurvatat is carries forward into the Younger Avesta. The Younger Avestan texts allude to their respective guardianships of plant life and water (comparable with the Gathic allusion to sustenence), but these identifications are only properly developed in later tradition. These associations with also reflect the Zoroastrian cosmological model in which each of the Amesha Spentas is identified with one aspect of creation.

Like the other Amesha Spentas also, Ameretat is already attested in the Gathas, the oldest texts of the Zoroastrianism and considered to have been composed by Zoroaster himself. And like most other principles, Ameretat is not unambiguously an entity in those hymns.

Through the association with plants and water, Ameretat and Haurvatat are consequently identified with food and drink, and traditionally it was out of respect for these two Amesha Spentas that meals were to be taken in silence

According to the cosmological legends of the Bundahishn, when Angra Mainyu (MP: Ahriman) withered the primordial plant, Ameretat crushed it to pulp and mixed it with water. Tishtrya then took the water and spread it over the world as rain, which in turn caused a multitude of other plants to grow up.
