Tithi-vicara
Determination of Tithi for Fasts, Parana, and Pitri Rites
हानिं च संततेर्भूपदौर्भाग्यं समवाप्नुयात् । एतच्छ्रुतं मया विप्राः कृष्णद्वैपायनात्पुरा ॥ १३ ॥
hāniṃ ca saṃtaterbhūpadaurbhāgyaṃ samavāpnuyāt | etacchrutaṃ mayā viprāḥ kṛṣṇadvaipāyanātpurā || 13 ||
王よ、その者は子孫の損失を被り、また王権より不運を招くであろう。おお婆羅門たちよ、これはかつてクリシュナ・ドヴァイパーヤナ(ヴィヤーサ)から私が聞いたことである。
Narada (narrating an earlier teaching heard from Vyasa)
Vrata: none
Primary Rasa: bhayanaka
Secondary Rasa: shanta
It warns that adharma brings both personal suffering (loss of lineage) and worldly repercussions (misfortune connected with rulers), while also grounding the teaching in the authoritative Purāṇic lineage via Vyāsa.
By implication, it supports bhakti-based dharma: devotion is not isolated from conduct—one’s faith must align with righteous behavior to avoid destructive karmic results affecting family and social standing.
Not a direct Vedāṅga lesson; the practical takeaway is dharma-nīti (ethical discipline) and awareness of pratyavāya (negative consequences) that Purāṇas often attach to ritual or moral violations.
