This verse maps specific lunar days (tithis) to presiding deities, showing that rituals and worship gain appropriateness and potency when aligned with the tithi’s deity.
It explicitly includes the Pitṛs on the fifteenth tithi, indicating that ancestral propitiation is especially relevant on that lunar day alongside worship of Brahmā and other Pitṛ-deities.
Use the lunar calendar to time worship: Viṣṇu devotion on Dvādaśī, Śiva on Caturdaśī, and include Pitṛ remembrance/offerings on the fifteenth tithi as appropriate to one’s tradition.
