Matsya Purana — Śrāddha Procedure: Types
नित्यं नैमित्तिकं काम्यं त्रिविधं श्राद्धमुच्यते नित्यं तावत्प्रवक्ष्यामि अर्घ्यावाहनवर्जितम् //
nityaṃ naimittikaṃ kāmyaṃ trividhaṃ śrāddhamucyate nityaṃ tāvatpravakṣyāmi arghyāvāhanavarjitam //
Śrāddha is said to be of three kinds—daily (nitya), occasional (naimittika), and desire-motivated (kāmya). First I shall explain the daily śrāddha, performed without the arghya offering and without formal invocation (āvāhana).
This verse is not about pralaya; it classifies śrāddha (ancestor rites) and introduces the daily (nitya) form, focusing on ritual discipline rather than cosmic dissolution.
It directly supports gṛhastha-dharma: maintaining regular ancestral observances. Even rulers are expected to uphold pitṛ-dharma, but the verse specifically frames a practical, daily śrāddha model.
The significance is ritual: the nitya-śrāddha described here is performed without arghya and without formal āvāhana, implying a simplified daily rite distinct from more elaborate ceremonial śrāddhas.
