Agni Deva was Brahma Manasa Putra (the mind-born son). From Swaha Devi, Agni begot three sons viz. ‘Paavaka’ (Dakshinaagni), ‘Pavamaan’ (Garhapatya), and ‘Shuchi’ (Aahavaniya) who are also known as Agni. Paavaka is also called ‘Vaidyut’ or produced from the currents of water, Paavana as ‘Nirmathya’ or created by Nirmathana (friction) and Shuchi is ‘Soura’ or created purely from Surya’s radiation. All the Agnis are stated to be of ‘Sthira Swabhava’ or of stable nature. Pavamaan’s son is called ‘Kavyavahan’; Paavak’s son is ‘Saharaksha’ and Shuchi’s son’s name is ‘Havyavahana’. Devata’s Agni is Havyavaah, who was Brahma’s first son. Saharaksha is the Agni of Asuras, while Kavyavaahan is the Agni of Pitru Devas. Thus the three Agnis are of Deva-Asura- Pitaras and their progeny-sons and grandsons-are as follows: Pavana’s son or the grandson of Brahma is known as ‘Brahmaodanaagni’ called ‘Bharat’; ‘Vaiswanara Agni’ carries Havya for hundred years; if ‘Pushkar’/ Aakash (Sky) is resorted to ‘Manthana’ (skimming), Athavarka Rupa’s Agni was created and that Agni is called ‘Dadhyangaartha Varna’ or Dakshinagni.

The Ahavaniya Agni which is the favourite of Devas and Brahmana’s too got divided into sixteen parts int Kaveri, Krishna veni, Narmada, Yamuna, Godavari, Vitasta or Jheelam, Chandrabhaga, Iravati, Vipaasha, Kaushiki (Kosi), Shatadru (Satlaj), Sarayu, Sita, Manaswini, Hladini and Pavana. The Agni which emerges from these Rivers is called ‘Dhishnu’ or ‘Dhishnya’, which caters to the purposes of Yagnas on the banks of these Rivers. Thus this Agni moves about to the banks of various Rivers to facilitate various punya Karyas by the names of ‘Vibhu’, ‘Pravaahan’, ‘Agnirgha’ and such other Dhishnu Rupas. In addition, there are certain ‘Anirdeshya’ and ‘Anivarya’ (unforeseen and inevitable) circumstances, when ‘Vasavi’ Agni also known as ’Kushanu’ is always available on the northern part of alternative Vedika or Platform of Yagnas. This Vasavi Agni has eight sons whom Brahmanas venerate, viz. Barhish (hotriya Agni Havyavahan), Pracheta (Samsahayak), Vishwadeva (Brahmanaachhamsi), ‘Swambhu’Agni called Setu; Avabhruta Agni originating from Varuna, Hridaya nama Agni or popularly known as ‘Jatharaagni’originating from the food items, Manumaani Agni which is Badabaagni emerging from deep Seas and Saharakshak Agni residing in households fulfilling desires of human beings. Besides, Agnis are meant for Kaamna Purti (fulfillment) or to those who perform Yagnas viz. Rakshoha Agnis also known as ‘Yatikritas’. Additionaly there are eight Agnis viz. Surabhi, Vasuratna, Naada, Haryaswa, Rukmavaan, Pravagya, and Kshemavan who were all the progeny of Shuchi.
