na dadyad amisam sraddhe
na cadyad dharma-tattvavit
muny-annaih syat para pritir
yatha na pasu-himsaya
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
A person fully aware of religious principles should never offer anything like meat, eggs or fish in the sraddha ceremony, and even if one is a ksatriya, he himself should not eat such things. When suitable food prepared with ghee is offered to saintly persons, the function is pleasing to the forefathers and the Supreme Lord, who are never pleased when animals are killed in the name of sacrifice.
