Matsya Purana — Sādhāraṇa Śrāddha: General Ancestral Rite
षण्मासं छागमांसेन तृप्यन्ति पितरस्तथा सप्त पार्षतमांसेन तथाष्टाव् एणजेन तु //
ṣaṇmāsaṃ chāgamāṃsena tṛpyanti pitarastathā sapta pārṣatamāṃsena tathāṣṭāv eṇajena tu //
By goat-meat the Pitṛs (ancestors) remain satisfied for six months; by the meat of a ‘pārṣata’ animal they are satisfied for seven months; and by the meat of eṇa (antelope/deer) they are satisfied for eight months.
This verse does not discuss Pralaya; it belongs to Śrāddha-dharma and specifies how different meat offerings are believed to sustain the satisfaction of the Pitṛs for varying durations.
It guides householders (and rulers as exemplars of dharma) on appropriate Śrāddha offerings and their stated results, emphasizing ritual responsibility toward ancestors as part of gṛhastha-dharma.
The significance is ritual: it quantifies the phala (duration of Pitṛ-satisfaction) associated with specific food offerings used in Śrāddha rites.
