Vadavagni (Sanskrit: वाडवाग्नि, romanized: Vāḍavāgni, lit. 'mare-fire'), also referred to as Vadavanala (Sanskrit: वडवानल, romanized: Vaḍavānala) refers to a submarine fire embodied in the form of a destructive being in Hindu mythology.[1] It is described to be a being that manifested with the head of a mare, but a body of blazing flame.[2]
The Vadavagni is regarded to wander the seabed and consume its waters, awaiting the moment it could emerge and destroy the earth during the Pralaya, the dissolution of the earth at the end of an age.[3][4] Various legends regarding the origin and suppression of the Vadavagni exist in Hindu literature, most prominently the descent of the goddess Saraswati as the Sarasvati river.[5]
