"Give food, Give food. Give food", this is what Lord Krishna advises Yudhishtira in the Bhavishya Purana in his discourse on 'daanam' or the discipline of sharing."
"Yudhishtira asks Lord Krishna to enlighten him about the essence of Bhishma Pitamaha's erudite discourse on dharma in the 'santi parva' of the Mahabharata. Lord Krishna says: "The World, both animate and inanimate, is sustained by food. The giver of food is the giver of life and indeed of everything else. Therefore, one who is desirous of well-being in this world and beyond, should make special endeavours to give food. Also Food should be offered with venerable hospitality to the old, the child, and the tired traveller".
