MADHUKEET (MADHU and KAITABHA)
My Lord destroyed the -demons without the practice of devotion including Sahasbahu, Madhukeet, Mehkhasa..... (Gauri M. l, p. 224) Episode: Madhu and Kaitabha were two formidable demons, who sprung from the ear of Vishnu, when he;;was sunk in his sleep of contemplation (Yoganidra) at the end of the kalpa. Brahma created gods and demons both, who began to fight with each other. The Vedic incarnations were used as weapons by the gods. Seeing this, the demons made up their mind to steal the Vedas. Madhu and Kaitabha, aided by Maya, east a spell on the gods and ran away with the Vedas and hid them at the bottom of the ocean.
The gods were unable to perform the rites without the Vedas and Brahma was incapable of creation. At that time, Shakti, the female power of Shiva helped Vishnu in the recovery of the Vedas. Vishnu assumed the form of a boar and brought back the Vedas. See : Das Avatars (boar incarnation).
