Matsya Purana — Ekoddiṣṭa Śrāddha
द्वितीये ऽह्नि पुनस्तद्वद् एकोद्दिष्टं समाचरेत् आवाहनाग्नौकरणं दैवहीनं विधानतः //
dvitīye 'hni punastadvad ekoddiṣṭaṃ samācaret āvāhanāgnaukaraṇaṃ daivahīnaṃ vidhānataḥ //
On the second day as well, one should perform the Ekoddiṣṭa-śrāddha in the same manner, according to the prescribed rule—carrying out the invocation and the fire-rite, but omitting the offerings to the gods, for it is directed solely to the departed.
This verse does not address Pralaya; it gives a procedural rule for the second-day Ekoddiṣṭa-śrāddha, focusing on correct ritual performance rather than cosmology.
It frames a householder’s dharma after a death in the family: on the second day one should repeat the Ekoddiṣṭa rite properly, emphasizing continuity of duty and fidelity to injunction (vidhānataḥ).
Ritually, it specifies a daivahīna (deity-portion omitted) Ekoddiṣṭa-śrāddha, including āvāhana (invocation) and agni-related acts—marking it as a focused offering to a single departed person rather than a mixed deva–pitṛ ceremony.
