Mbh 13.132.3a

"'"The (eight) elephants standing in the eight quarters said, 'On the auspicious eighth day of the dark fortnight in the month of Karttika when the constellation Aslesha is in the ascendant, one should make gifts of treacle and rice. Casting aside wrath, and living on regulated diet, one should make these offerings at a Sraddha, uttering these mantras the while--"Let Valadeva and other Nagas possessed of great strength, let other mighty snakes of huge bodies that are indestructible and eternal, and let all the other great snakes that have taken their birth in their race, make Vali offerings to me for the enhancement of my strength and energy. Verily, let my strength be as great as that of the blessed Narayana when he raised the submerged Earth!"--Uttering these mantras, one should make Vali offerings upon an ant-hill. When the maker of day retires to his chambers in the west, upon the ant-hill selected should offerings be made of raw sugar and rice. The ant-hill should previously be scattered with Gajendra flowers. Offerings should also be made of blue cloths and fragrant unguents. If offerings are made in this way, those beings that live in the nether regions, bearing the weight of the upper regions upon their heads or shoulders, become well-pleased and gratified. As regards ourselves, we also do not feel the labour of upholding the Earth, in consequence of such offerings being made to us. Afflicted with the burden we bear, even this is what we think (beneficial for men), without the slightest regard for selfish concerns. Brahmanas and Kshatriyas and Vaisyas and Sudras, by observing this rule for a full year, fasting on each occasion, acquire great merits from such gifts. We think that the making of such Vali offerings on the ant-hill is really fraught with very superior merits. By making such offerings, one is regarded as doing the duties of hospitality for a hundred years to all the mighty elephants that exist in the three worlds.
