Qormusta Tengri (Qormusata Tngri "King of the Gods", also transliterated as Qormusta Tngri and Hormusta) is a god in Mongolian mythology and shamanism, described as the chief god of the 99 tngri and leader of the 33 gods. It is the same of Turkish deities / gods Hürmüz and Kormos Han.
According to Walther Heissig, the group of 33 gods led by Qormusata Tngri exists alongside the well-known group of 99 tngri. Qormusata Tngri is to be equated with Ahura Mazda, the chief Iranian god, and with Esrua, who in turn is Brahma, the Hindu god of creation. The Indian influence may explain the 33 gods, analogous with Indra (to whom Michael York compares him, as a more active being) and his 33 planets (or gods). Qormusata Tngri leads those 33, and in early Mongolian texts is also mentioned as leading the 99 tngri. He is connected to the origin of fire: "Buddha struck the light and 'Qormusata Tngri lit the fire'." A Mongolian fable of a fox describes a fox so clever that even Qormusata Tngri (as the head of the 99 tingri) falls prey to him; in a Mongolian folktale, Boldag ugei boru ebugen ("The impossible old man, Boru"), he is the sky god with the crow and the wolf as his "faithful agents".
Qormusata Tngri's relatively recent entrance into the Mongolian pantheon is also indicated by the attempts on the part of Mergen Gegen Lubsangdambijalsan (1717-1766?) to replace earlier shamanist gods in the liturgy with five Lamaist gods including Qormusata Tngri. In one text, he is presented as the father of the 17th-century cult figure Sagang Sechen, who is at the same time an incarnation of Vaiśravaṇa, one of the Four Heavenly Kings in Buddhism.
In Manichaeism, the name Ohrmazd Bay ("god Ahura Mazda") was used for the primal figure Nāšā Qaḏmāyā, the "original man" and emanation of the Father of Greatness (in Manicheism called Zurvan) through whom after he sacrificed himself to defend the world of light was consumed by the forces of darkness. Although Ormuzd is freed from the world of darkness his "sons", often called his garments or weapons, remain. His sons, later known as the World Soul after a series of events will for the most part escape from matter and return again to the world of light where they came from.
