Mbh 12.340.7b

This narrative, O king, is really the essence of the hundreds of other narratives that thou hast heard from me. In days of yore, O monarch, the deities and the Asuras, uniting together, churned the Ocean and raised the Amrita. After the same manner, the Brahmanas, uniting together in days of yore, churned all the scriptures and raised this narrative which resembles nectar. He who frequently reads this narrative, and he who frequently listens to it, with concentrated attention, in a retired spot, and filled with devotion, succeeds in becoming a denizen, possessed of lunar complexion, of the spacious island known by the name of White Island. Without doubt, such a man succeeds in entering into Narayana of a thousand rays. A sick person, by listening to this narrative from the beginning, becomes freed from his illness. The man that simply desires to read or listen to this narrative obtains the fruition of all his wishes. To devoted worshipper, by reading or listening to it, attains to the high end that is reserved for devoted worshippers. Thou also, O monarch, shouldst always adore and worship that foremost of all Beings. He is the father and the mother of all creatures, and He is an object of reverence with the entire universe. Let the illustrious and Eternal God of the Brahmans, viz., Janarddana of high intelligence, be gratified with thee, O Yudhishthira of mighty arms!"'
