Tithi-vicara
Determination of Tithi for Fasts, Parana, and Pitri Rites
एतस्मात्कारणाद्विप्राः प्रत्यूषे स्नानमाचरेत् । पितृतर्पणसंयुक्तं न दृष्ट्वा द्वादशीदिनम् ॥ २३ ॥
etasmātkāraṇādviprāḥ pratyūṣe snānamācaret | pitṛtarpaṇasaṃyuktaṃ na dṛṣṭvā dvādaśīdinam || 23 ||
ଏହି କାରଣରୁ, ହେ ବିପ୍ରମାନେ, ପ୍ରତ୍ୟୂଷେ ସ୍ନାନ କର; ପିତୃତର୍ପଣ ସହିତ ଦ୍ୱାଦଶୀ ଦିନକୁ ଅଦୃଷ୍ଟ କରି ଯିବାକୁ ଦିଅନି।
Sanatkumara (in instruction to Narada, addressing brāhmaṇas as the audience)
Vrata: Dvādaśī (as part of Ekādaśī observance cycle)
Rasa: {"primary_rasa":"shanta","secondary_rasa":"karuna","emotional_journey":"A sober, careful insistence: because the stakes are real, bathe at dawn with pitṛ-tarpaṇa and do not let Dvādaśī slip away—concern for spiritual negligence."}
It stresses that Dvādaśī is not merely a calendar marker but a sacred tithi to be consciously observed through purificatory dawn-bathing and reverential pitṛ-tarpaṇa, integrating personal purity with ancestral duty.
By insisting on mindful observance of Dvādaśī (commonly linked with Hari-related vrata sequences around Ekādaśī), the verse supports bhakti as disciplined devotion expressed through timely, sattvic daily rites rather than casual or neglected practice.
It highlights tithi-based ritual timing (Jyotiṣa/kalā-vidhi in practice) and correct daily rite sequencing—pratyūṣa-snana followed by pitṛ-tarpaṇa—showing how observances are anchored to lunar days like Dvādaśī.
