Nāndīmukha-śrāddha (Prosperity Rites), Preta-kriyā, Aśauca, Ekoddiṣṭa, and Sapiṇḍīkaraṇa Framework
एको ऽर्घ्यस् तत्र दातव्यस् तथैवैकं पवित्रकम् प्रेताय पिण्डो दातव्यो भुक्तवत्सु द्विजातिषु
eko 'rghyas tatra dātavyas tathaivaikaṃ pavitrakam pretāya piṇḍo dātavyo bhuktavatsu dvijātiṣu
There, a single arghya (water-offering) should be presented, and likewise a single pavitraka (ring of sacred kuśa-grass). And when the twice-born have completed their meal, a piṇḍa (funerary rice-ball) is to be offered for the preta—so that the rite proceeds in due order, according to dharma.
Sage Parāśara (in instruction to Maitreya)
Speaker: Parasara
Topic: Specific Ekoddiṣṭa components: single arghya, single pavitraka, and timing of piṇḍa after dvija-feeding
Teaching: Ethical
Quality: precise and procedural
Concept: Ekoddiṣṭa is marked by singularity and order: one arghya, one pavitraka, and a piṇḍa offered to the preta after the twice-born have eaten.
Vedantic Theme: Dharma
Application: Let acts of remembrance be simple, sincere, and properly sequenced—prioritize meaning over excess.
Vishishtadvaita: Ritual service (kainkarya) is structured; the same dharma that honors devas also compassionately supports the jīva’s transition, reflecting an ordered, personal cosmos under the Lord.
This verse emphasizes a disciplined, minimal, and ordered śrāddha: one arghya and one pavitraka sanctify the act, and the piṇḍa specifically sustains the preta, aligning the rite with dharma.
Parāśara places the offering to the preta after the dvijas have eaten, showing that ritual efficacy depends on proper sequence and social-sacral order.
Though Vishnu is not named in the verse, the Vishnu Purana presents dharma-based rites like śrāddha as part of the divinely sustained cosmic order under Vishnu’s sovereignty.
