Tithi-vicara
Determination of Tithi for Fasts, Parana, and Pitri Rites
न तत्रोदयिनी ग्राह्या दैवस्योदयिकी तिथिः । प्रत्यहं शोधयेत्प्राज्ञस्तिथिं दैवज्ञचिंतकात् ॥ १६ ॥
na tatrodayinī grāhyā daivasyodayikī tithiḥ | pratyahaṃ śodhayetprājñastithiṃ daivajñaciṃtakāt || 16 ||
この件では、日の出に基づく「ウダイニー」の取り方を採用してはならない。むしろ聖なる誓戒と儀礼においては、日の出を基準として定められたティティを取るべきである。ゆえに賢者は、毎日、暦算に通じた占星家によりティティを確かめよ。
Narada (teaching in a ritual-technical context)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It emphasizes that dharmic observances require correct sacred time (kāla-śuddhi); accurate tithi determination safeguards the purity and efficacy of rites and vows.
While not directly preaching bhakti, it supports devotion by insisting that vrata and pūjā offered with proper tithi (right time) are performed in an orderly, scripture-aligned way, strengthening disciplined worship.
Vedāṅga Jyotiṣa: the practical computation/verification of tithi with reference to sunrise, and the need to consult a competent daivajña for daily calendrical accuracy.
