Tithi-vicara
Determination of Tithi for Fasts, Parana, and Pitri Rites
तिथिप्रमाणं विप्रेंद्राः क्षपाकरदिवाकरौ । चंद्रार्कचारविज्ञानात्कालं कालविदो विदुः ॥ १७ ॥
tithipramāṇaṃ vipreṃdrāḥ kṣapākaradivākarau | caṃdrārkacāravijñānātkālaṃ kālavido viduḥ || 17 ||
Wahai yang terbaik antara para brāhmaṇa, ukuran tithi ditentukan oleh Bulan dan Matahari. Dengan mengetahui perjalanan Bulan dan Matahari, para arif tentang kala memahami hakikat waktu itu sendiri.
Narada (teaching the assembled sages/brāhmaṇas)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It frames sacred observance as aligned with cosmic order: knowing tithi through Sun–Moon motion ensures vratas and rites are performed at the correct time, honoring ṛta (the lawful rhythm of the universe).
Bhakti practices (fasts, pūjā, Ekādaśī-like observances) depend on proper timing; the verse supports devotion by grounding worship in accurate tithi reckoning rather than guesswork.
Jyotiṣa Vedāṅga: determining tithi and kāla by calculating/observing the Moon’s and Sun’s courses (candrārka-cāra), a key tool for calendrics and ritual scheduling.
