Spenta Armaiti

In Zoroastrianism, Spənta Ārmaiti (Avestan for "Holy Devotion") is one of the Amesha Spentas, the six divine sparks. While older sources present the Amesha Spentas more as abstract entities, in later sources, Spenta Armaiti is personified as a female divinity. She is associated with earth.

In the Armenian mythology, her name appears as Sandaramet (Armenian: Սանդարամետ).

In the Zoroastrian calendar, she is associated with the twelfth month (Persian: سپندارمذ‎‎ Spendārmad) and the fifth day of the month. The fifth day of the twelfth month is hence her holy day, Sepandārmazgān.
