Agni — Sacred Messenger of the Flame
Agni (अग्नि) is the fire god and divine messenger between gods and humans in Indian Vedic mythology. The name means 'fire' in Sanskrit, and during the Vedic era (1500-500 BCE) Agni was the second most praised god after Indra, with the first hymn of the Rigveda dedicated to him. Depicted as multi-headed with three heads and seven tongues, riding various sacred mounts including ram, horse, and parrot. His core role is the purifying flame — the cosmic intermediary who burns offerings of cattle, grains, and ghee that humans dedicate to the gods, transmitting them to the heavens. For this reason, Agni's altar stands at the center of every Vedic ritual. Governing both purification and annihilation, anything touched by his flames becomes pure or burns to nothing. In later Hinduism, he is one of the eight Lokapala guardian gods, protecting the southeast direction. Japanese Buddhism's Katen is a direct adaptation of Agni.
Origin
One of the most frequently mentioned deities in Vedic literature alongside Indra. Central to yajña (fire sacrifice) rites, he carries human prayers to the divine realm through flame. Over 200 hymns in the Rigveda are dedicated to him.
