Mbh 3.218.1b

He is free from all taint and is not defiled by sin, and is the regulator of time. That fire has another name Nishkriti, because he accomplished the Nishkriti (relief) of all blatant creatures here. When properly worshipped he vouchsafes good fortune. His son is called Swana, who is the generator of all diseases; he inflicts severe sufferings on people for which they cry aloud, and moves in the intelligence of the whole universe. And the other fire (Vrihaspati’s third son) is called Viswajit by men of spiritual wisdom. The fire, which is known as the internal heat by which the food of all creatures is digested, is the fourth son of Vrihaspati known through all the worlds, O Bharata, by the name of Viswabhuk. He is self-restrained, of great religious merit, and is a Brahmacharin and he is worshipped by Brahmanas at the Paka-sacrifices. The sacred river Gomati was his wife and by her all religious-minded men perform their rites. And that terrible water-drinking sea fire called Vadava is the fifth son of Vrihaspati. This Brahmic fire has a tendency to move upwards and hence it is called Urdhvabhag, and is seated in the vital air called Prana. The sixth son is called the great Swishtakrit; for by him oblations became swishta (su, excellently, and ishta, offered) and the udagdhara oblation is always made in his honour. And when all creatures are claimed, the fire called Manyauti becomes filled with fury. This inexorably terrible and highly irascible fire is the daughter of Vrihaspati, and is known as Swaha and is present in all matter. (By the respective influence of the three qualities of sattwa, rajas and tamas, Swaha had three sons). By reason of the first she had a son who was equalled by none in heaven in personal beauty, and from this fact he was surnamed by the gods as the Kama-fire.[65] (By reason of the second) she had a son called the Amogha or invincible fire, the destroyer of his enemies in battle.
