Mbh 13.68.5

"'"Yama said, 'Do thou hear, O regenerate Rishi, the excellent ordinances regarding gifts. The gift of sesame seeds is a very superior one. It produces everlasting merit. O foremost of regenerate ones, one should make gifts of as much sesame as one can. By making gifts of sesame every day, one is sure to attain the fruition of one's every wish. The gift of sesame at Sraddhas is applauded. Verily the gift of sesame is a very superior one. Do thou make gifts of sesame unto the Brahmanas according to the rites ordained in the scriptures. One should on the day of the full moon of the month of Vaisakha, make gifts of sesame unto the Brahmanas. They should also be made to eat and to touch sesame on every occasion that one can afford. They that are desirous of achieving what is beneficial to them should, with their whole souls, do this in their houses.[347] Without doubt, men should similarly make gifts of water and establish resting places for the distribution of drinking water.[348] One should cause tanks and lakes and wells to be excavated. Such acts are rare in the world, O best of regenerate persons! Do thou always make gifts of water. This act is fraught with great merit. O best of regenerate persons, thou shouldst establish resting places along the roads for the distribution of water. After one has eaten, the gift unto one should especially be made of water for drink.'"
