Vaishvanara is one of the names of Agni, the fire god in
Hinduism. There are Rig Vedic mantras (IX. 66) dedicated to Vaishvanara Agni.
Vaishvanara Agni has various forms and lives in three
abodes. He is described as having red tongues, seven faces, a huge mouth, red
neck, tawny eyes, bright hair and golden seed. He is the dispeller of darkness.
He destroys demons and hostile powers, possesses excellent qualities
and transcendental powers.
Vedas also state that fire by the name of Vaishvanara
resides in the stomach of each being; this is combined with the life force
(prana) causing the activity of digestion and assimilation of food.
