Matsya Purana — Śrāddha Procedure: Types
श्राद्धेषु भोजनीया ये ये च वर्ज्या द्विजातयः कस्मिन्वासरभागे वा पितृभ्यः श्राद्धमाचरेत् //
śrāddheṣu bhojanīyā ye ye ca varjyā dvijātayaḥ kasminvāsarabhāge vā pitṛbhyaḥ śrāddhamācaret //
At śrāddhas, which twice-born persons are fit to be fed, and which are to be avoided? And at what division of the day should one perform the śrāddha for the Pitṛs (ancestors)?
This verse does not discuss pralaya; it shifts the focus to dharma—specifically the correct procedure for ancestral śrāddha, emphasizing ritual eligibility and timing.
It frames a key gṛhastha (householder) duty: honoring ancestors through śrāddha with proper discrimination—inviting qualified dvijātis and avoiding unfit recipients, and performing the rite at the proper time of day.
The significance is ritual (not architectural): it introduces śrāddha-vidhi questions—who may be fed at śrāddha and the correct vāsara-bhāga (time division) for offerings to the Pitṛs.
