Agni

Agni is attested from the earliest Vedic layer (notably the Rigveda) as one of the principal invoked deities. Etymologically deriving from Proto‑Indo‑European *h₁n̥gʷnis (cognate with Latin ignis, Lithuanian ugnis, Old Slavic огнь, etc.), Agni is described in Vedic and Brahmanical texts as arising as the primal fire and as the first to appear in the universe (traditional etymologies in the Brahmanas derive his name from notions of 'first' and of movement). Over time his conceptual role evolves: in the Vedic period he is predominantly an external sacrificial god and mediator; in Upanishadic and post‑Vedic literature his identity is increasingly internalized and metaphysical, becoming a metaphor for inner transformative energy, knowledge, and an immortal principle in humans. The Vedic motif of Agni's triple presence (terrestrial hearth fire, atmospheric lightning, and celestial sun) underpins his role as messenger between humans and the gods.

Sources supplied do not record a single fixed anthropomorphic iconography but Vedic hymns and later descriptions portray Agni with luminous, flame‑related imagery: epithets such as Pāvaka (sanctifier), Havyavāhana (bearer of sacrificial butter), Saptajihvi (having seven tongues/flames), Chitrabhānu (variegated light), Jvalana (ever‑glowing) and Dhumaketu (crowned with smoke/fire) present a poetic picture of a radiant, tongued/crowned flame. Temple tradition places Agni as guardian of the southeast corner, further associating him with directional and architectural loci. Thus the textual appearance is best described as a radiant, multiform fire — tongued, crowned, and luminous — rather than a single standardized human figure (iconographic specifics are not given in the supplied extracts).

Textual sources describe Agni primarily in functional, ritual, and cosmological terms rather than as a catalogue of combative powers. He is the ritual consumer and transformer of offerings (Hutāśana), the mouth of the gods who conveys havis through the homa (votive/sacrificial) ritual (Havyavāhana), and therefore a mediator/messenger between humans and deities due to his triple presence (hearth, atmosphere/lightning, and sun). He sanctifies and witnesses rites of passage (for example the Saptapadi wedding rite and the Upanayana initiation), participates in household and sacrificial life (hearth fire, altar fire, cremation pyre), and functions metaphysically as the power that consumes ignorance and brings illumination, the fire of rebirth, and digestive/inner fire. Epithets and contexts imply rapid consumption (many‑tongued flame), purifying action, and a life‑transforming role, but sources in the provided material focus on ritual and symbolic operations rather than discrete 'magical' capacities.
