13.92.3

nivāpairdīyamānaiśca cāturvarṇyena bhārata |
tarpitāḥ pitaro devāste nānnaṃ jarayanti vai || 3 ||

"Bhishma said, 'After Nimi had acted in the way described above, all the great Rishis began to perform the sacrifice in honour of the Pitris (called the Sraddha) according to rites laid down in the ordinance. Firmly devoted to the discharge of all duties, the Rishis, having performed Sraddhas, began to also offer oblations (unto the Pitris) of sacred waters, with attention. In consequence, however, of the offerings made by persons of all classes (unto the Pitris), the Pitris began to digest that food. Soon they, and the deities also with them, became afflicted with indigestion. Indeed, afflicted with the heaps of food that all persons began to give them, they repaired to the presence of Soma. Approaching Soma they said, 'Alas, great is our affliction in consequence of the food that is offered to us at Sraddhas. Do thou ordain what is necessary for our ease.' Unto them Soma answered, saying, 'If, ye gods, ye are desirous of obtaining ease, do ye repair then into the abode of the Self-born. Even he will do what is for your good.' At these words of Soma, the deities and the Pitris then proceeded, O Bharata, to the Grandsire where he was seated on the summit of the mountains of Meru.'
