Mbh 13.129.1b

That man who, rising at early dawn and purifying himself by a bath, attires himself in white robes and with the concentrated attention makes gifts unto Brahmanas of vessels full of sesame seeds, who makes offerings unto the Pitris of water with sesame seeds and honey, and who gives lamps as also the food called Krisara acquires substantial merits. Listen to me as I say what those merits are. The divine chastiser of Paka has ascribed these merits to the gift of vessels of copper and brass filled with sesame seeds. He who makes gifts of kine, he who makes gifts of land that are productive of eternal merit, he who performs the Agnishtoma sacrifice with copious presents in the form of Dakshina to the Brahmanas, are all regarded by the deities as acquiring merits equal to those which one acquires by making gifts of vessels filled with sesame seeds. Gifts of water with sesame seeds are regarded by the Pitris as productive of eternal gratification to them. The grandsires all become highly pleased with gifts of lamps and Krisara. I have thus recited the ancient ordinance, laid down by the Rishis, that is highly applauded by both the Pitris and the deities in their respective regions.'"'"
