Srimad Bhagavatam 10.23.7-9
Text 7
ramacyutau vo lashato bubhukshitau
tayor dvija odanam arthinor yadi
sraddha ca vo yacchata dharma-vittamah
TRANSLATION
Lord Rama and Lord Acyuta are tending Their cows not far from here. They are hungry and want you to give Them some of your food. Therefore, O brahmanas, O best of the knowers of religion, if you have faith please give some food to Them.
Text 8
sautramanyas ca sattamah
anyatra dikshitasyapi
nannam asnan hi dushyati
TRANSLATION
Except during the interval between the initiation of the performer of a sacrifice and the actual sacrifice of the animal, O most pure brahmanas, it is not contaminating for even the initiated to partake of food, at least in sacrifices other than the Sautramani.
Text 9
srinvanto 'pi na susruvuh
kshudrasa bhuri-karmano
balisa vriddha-maninah
TRANSLATION
The brahmanas heard this supplication from the Supreme Personality of Godhead, yet they refused to pay heed. Indeed, they were full of petty desires and entangled in elaborate rituals. Though presuming themselves advanced in Vedic learning, they were actually inexperienced fools.
