annamūrjaskaraṃ loke prāṇāścānne pratiṣṭhitāḥ |
annena dhāryate sarvaṃ viśvaṃ jagadidaṃ prabho || 7 ||

"Narada said, 'The deities and all the Rishis applaud food. The course of the world and the intellectual faculties have all been established on food. There has never been, nor will be any gift that is equal to the gifts of food. Hence, men always desire particularly to make gifts of food. In this world, food is the cause of energy and strength. The life-breaths are established on food. It is food that upholds the wide universe, O puissant one. All classes of men, householders and mendicants and ascetics, exist, depending upon food. The life-breaths depend upon food. There is no doubt in this. Afflicting (if need be) one's relatives, one is desirous of one's own prosperity, should make gifts of food unto a high-souled Brahmana or a person of the mendicant order. That man who makes a gift of food unto an accomplished Brahmana who solicits the same, secures for himself in the world to come wealth of great value. The householder who is desirous of his own prosperity should receive with reverence a deserving old man that is spent with toil while proceeding on his way far from home, when such a man honours the householder's abode with his presence. That man who, casting off wrath that overleaps every bound and becoming righteous in disposition and freed from malice, makes gifts of food, is sure to attain to happiness, O king, both here and hereafter. The householder should never disregard the man that comes to his abode, nor should he insult him by sending him away.
