Brahmaa Jee went to Vishnu along with other Devtaa and prayed Him. Pleased with their worship, Vishnu said - "On Kaartik Shukla Prabodhinee Ekaadashee day, when only one Prahar (3 hours) night remains, whoever will worship me, they will come near me. Shankhaasur has kept all Ved in water. I will kill him and bring the Ved from him. From today, every year Ved and I will rest in water in Kaartik Maas. Since you have come on Ekaadashee, that is why this Tithi will be very dear to me. If anyone takes up Ekaadashee and Kaartik Maas Vrat, he will surely come to me."

Naarad Jee said - "After saying this, Vishnu fell in the hands of Muni Kashyap living on Vindhya Parvat assuming the form a fish. Muni kept him in his Kamandal, but it became smaller in size for that fish, so Muni took him to a pond, and in the end he had to take him to sea. There also he expanded his body and killed Shankhaasur. Carrying that Shankh (conch shell), He went to Badaree Van and said to Muni - "Go and find the Ved in sea, and bring them along with their secrets, till then I stay in Prayaag with Devtaa." All Muni recovered the Ved from the sea. Whichever number of Mantra a Muni recovered, he was regarded the Rishi of that Mantra section. The Muni went to Prayaag and gave the Ved to Brahmaa Jee."
