Śrāddha’s Cosmic Reach and Kāla-Nirṇaya (Sacred Timings): Amāvāsyā, Nakṣatra-Yoga, Tīrtha, and Minimum Offerings
मासि मास्य् असिते पक्षे पञ्चदश्यां नरेश्वर तथाष्टकासु कुर्वीत काम्यान् कालाञ् छृणुष्व मे
māsi māsy asite pakṣe pañcadaśyāṃ nareśvara tathāṣṭakāsu kurvīta kāmyān kālāñ chṛṇuṣva me
हे नरेश्वर, प्रतिमासं कृष्णपक्षस्य पञ्चदश्यां तथा अष्टकासु काम्यकर्माणि कुर्यात्; तेषां यथाकालं नियतकालांश्च मे शृणु।
Sage Parāśara (in instruction to Maitreya; addressing a kingly addressee in the verse)
This verse treats pañcadaśī of the kṛṣṇa-pakṣa as a regularly recurring, ritually potent time when kāmya (wish-oriented) observances are considered especially effective due to alignment with sacred lunar timing.
Parāśara frames ritual efficacy around calendrical precision—specific tithis and observance-days (like Aṣṭakā)—and instructs the listener to follow these recurring monthly markers as the authorized windows for such rites.
Even when the verse discusses kāmya rites, the Vishnu Purana’s broader stance is that kāla (time) and dharma operate under the sovereignty of the Supreme—Vishnu—so correct observance is ultimately participation in divinely ordered cosmic law.
