Matsya Purana — Pitṛ Worlds
एतान्यपि न देयानि पितृभ्यः प्रियमिच्छता पितॄन् प्रीणाति यो भक्त्या ते पुनः प्रीणयन्ति तम् //
etānyapi na deyāni pitṛbhyaḥ priyamicchatā pitṝn prīṇāti yo bhaktyā te punaḥ prīṇayanti tam //
Even these should not be offered to the Pitṛs by one who seeks what is dear (their favor). Whoever satisfies the ancestors with devotion—those Pitṛs, in turn, satisfy and bless him.
This verse is not about Pralaya; it teaches Pitṛ-dharma—proper conduct in ancestor rites—stating that devotion and correct offerings bring the Pitṛs’ favor.
It reinforces the householder’s (and by extension a king’s) duty to perform Śrāddha correctly: avoid improper offerings and cultivate bhakti, because ancestral satisfaction is linked to the performer’s welfare and prosperity.
The significance is ritual: in Śrāddha, certain items are prohibited; the verse emphasizes that sincere devotion and proper procedure are what truly please the Pitṛs and yield blessings in return.
