Mbh 13.62.2d

Those conversant with ancient history sing this verse in connection with the gift of earth. Hearing that verse Jamadagni's son (Rama) gave away the whole earth unto Kasyapa. The verse to which I refer is this, 'Receive me in gift. Give me away. By giving me away, thou (O giver) shall obtain me again!' That which is given away in this life is re-acquired in the next.[330] That Brahmana who recites this high declaration of the Vedas at the time of a Sraddha attains to the highest reward. A gift of earth is a high expiation for the sin of those puissant men who betake themselves to Atharvan rites for doing injuries to others. Indeed, by making a gift of earth one rescues ten generations of one's paternal and maternal race. That person who is even conversant with this Vedic declaration respecting the merits of a gift of earth, succeeds in rescuing ten generations of both his paternal and maternal families. The earth is the original source of all creatures (for it is from earth that all creatures derive their sustenance). It has been said that the deity of fire is the presiding genius of the earth. After the coronation ceremony has been performed of a king, this Vedic declaration should be re-cited to him, so that he may make gifts of earth and may never take away earth from a righteous person. Without doubt, the entire wealth owned by the king belongs to the Brahmanas. A king well-conversant with the science of duty and morality is the first requisite of the kingdom's prosperity. Those people whose king is unrighteous and atheistic in conduct and belief can never be happy. Such people can never sleep or wake in peace. In consequence of his acts of wickedness his subjects become always filled with anxiety. Protection of what the subjects already have and new acquisitions according to lawful means are incidents that are not noticeable in the kingdom of such a ruler. Those people, again, who have a wise and righteous king, sleep happily and wake up in happiness.
