Āścarya-kathana: Brāhmaṇa–Nāga Dialogue on Sūrya (Vivasvat) and the ‘Second Sun’ Phenomenon
ऋग्वेदपाठपठितं व्रतमेतद्धि दुश्चरम् । सुपर्णाच्चाप्यधिगतो धर्म एब सनातन:
ṛgvedapāṭhapaṭhitaṁ vratam etad dhi duścaram | suparṇāc cāpy adhigato dharma eṣa sanātanaḥ ||
毗湿摩波耶那说道：“此戒行以诵读与研习《梨俱吠陀》（Ṛgveda）为根基，确实难以奉行。而这永恒之法（dharma），亦是从苏帕尔那（迦楼罗）处所学得。”

Educational Q&A
The verse emphasizes that true dharma is both scripturally grounded (linked to Ṛgvedic recitation/study) and demanding in practice; it is presented as sanātana—perennial and authoritative—also transmitted through revered sources such as Suparṇa (Garuḍa).
Vaiśampāyana, continuing the discourse in Śānti Parva, underscores the difficulty of a particular vow/discipline associated with Vedic study and notes its traditional pedigree by stating that this eternal dharma was also learned from Suparṇa.
