Matsya Purana — Sādhāraṇa Śrāddha: General Ancestral Rite
एतच्चानुपनीतो ऽपि कुर्यात्सर्वेषु पर्वसु श्राद्धं साधारणं नाम सर्वकामफलप्रदम् //
etaccānupanīto 'pi kuryātsarveṣu parvasu śrāddhaṃ sādhāraṇaṃ nāma sarvakāmaphalapradam //
Even one who has not undergone the upanayana initiation should perform, on all parva (sacred junction) days, the śrāddha called “Sādhāraṇa”; it bestows the fruits of all desired aims.
This verse does not discuss pralaya; it focuses on dharma—specifically the permissibility and merit of performing a “sādhāraṇa” śrāddha on parva days.
It frames śrāddha as a broadly accessible duty: even someone lacking formal initiation may perform the sādhāraṇa śrāddha on sacred occasions, emphasizing inclusive ancestral obligation and merit-making relevant to householders and rulers alike.
The significance is ritual (not architectural): “Sādhāraṇa-śrāddha” is presented as a generally applicable śrāddha to be done on parva days, praised as yielding comprehensive desired results (sarvakāma-phala).
