FAQs
Sacred timing multiplies dharmic effort—merit gained on especially potent days becomes akṣaya (inexhaustible).
The broader context is Kāśī in the Kāśīkhaṇḍa, where time, worship, and merit are repeatedly magnified by the sanctity of the kṣetra.
No single rite is named; it implies performing dharmic acts (snāna, dāna, japa, pūjā) when Sunday coincides with saṃkrānti or an eclipse.
