Agni (Sanskrit: अग्नि Agni), pronounced " ăgˈnē ", is a Hindu deity, one of the most important of the Vedic gods. He is the god of fire <energy>  and the acceptor of sacrifices for onwards conveyance to other deities. The sacrifices made to Agni go to the deities because Agni is a messenger from and to the other gods. He is ever-young, because the fire is re-lit every day, and is immortal. In the Rig Veda (I.95.2), a Rishi prays - for the ten eternal powers to bless Tvashtr (the supreme mind which creates all things) with the birth of Agni which is a reference to the ten undisclosed powers that nourish Agni. Yaskacharya explains that the fire-god is called अग्नि (Agni) because he is अग्रणी (Agrani), the forward leader who is the ever awake disseminator of knowledge and the first principle of thought which manifests as Speech; it is carried at the front in all ritualistic undertakings (yajnas). Pippalāda, the sage of the Prashna Upanishad, merely highlights the एकायुः (the Sole person) status of Agni when he tells Kābandhi Katayāna – " That very one, Surya who is Aditya, rises up who is Prana and Agni, who is identified with all creatures and who is possessed of all fame. " The Vedic Rishis knew knowledge to be the quality of the Atman. Surya, Aditya, Prana and Agni stand for the Atman who reveals itself as knowledge by the all-illuminating bright rays of light and who reveals itself as objects cognized by the mind and described through speech (Rig Veda X.135.7). According to the Puranas, the origin of Krittika nakshatra (the Pleiades star-cluster) ruled by Agni, and the birth of Kartikeya is associated with Agni. The Death-conquering Agni-rahasya vidya, which was received by Prajapati from the self-existent Brahman, is detailed in the tenth kanda of the Shatapatha Brahmana. During Vedic times, animal sacrifices to propriate Agni were frequently made. Agni is also referred by the name Chagavahana.
