Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
If one arranges to feed many brahmanas or relatives during the sraddha ceremony, there will be discrepancies in the time, place, respectability and ingredients, the person to be worshiped, and the method of offering worship.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Narada Muni has prohibited unnecessarily gorgeous arrangements to feed relatives or brahmanas during the sraddha ceremony. Those who are materially opulent spend lavishly during this ceremony. Indians spend especially lavishly on three occasions — at the birth of a child, at marriage and while observing the sraddha ceremony — but the sastras prohibit the excessive expenditures involved in inviting many brahmanas and relatives, especially during the sraddha ceremony.
