Hayagriva

Hayagriva, (हयग्रीव IAST , horse-necked one), is a Hindu deity, the horse-headed avatar of Vishnu. The purpose of this incarnation was to slay a danava also named Hayagriva (A descendant of Kashyapa and Danu), who had the neck of a horse and the body of a human. Hayagriva is an avatara of the god Vishnu. He is worshipped as the god of knowledge and wisdom, with a human body and a horse's head, brilliant white in color, with white garments and seated on a white lotus. Symbolically, the story represents the triumph of pure knowledge, guided by the hand of Divinity, over the demonic forces of passion and darkness. Vedanta Desika's dhyāna-śloka (meditative verse) on Hayagriva typifies this deity's depiction in Hindu iconography: He has four hands, with one in the mode of bestowing knowledge; another holds books of wisdom, and the other two hold the Conch and Discus. His beauty, like fresh cut crystal, is an auspicious brilliance that never decays. May this Lord of speech who showers such cooling rays of grace on me be forever manifest in my heart! In several other sources he is a white horse who pulls the sun into the sky every morning. In others such as the great epic Taraka-battle where the demigods are fallen on and attacked by the Danava's [demons], Vishnu appears as a great ferocious warrior called Hayagriva when he comes to their aid. It says: "Hayagriva appears in his chariot, drawn by 1,000 powerful steeds, crushing the enemies of the gods beneath him!" There are many other references to Hayagriva throughout the Mahabharata. It is said that Vishnu comes from battle as a conqueror in the magnificent mystic form of the great and terrible Hayagriva: The great Hayagriva having been praised in this way by the different saints and ascetics, assumes a great white horses head. The verda’s [mantras] made up his shape, his body built of all the great demigods; in the middle of his head was Shiva, in his heart was Brahmā; the rays of sun (Marichi) were his mane, the sun and moon his eyes; the Vasus and Sadhyas were his legs, in all his bones were the demigods.
