Āścarya-kathana: Brāhmaṇa–Nāga Dialogue on Sūrya (Vivasvat) and the ‘Second Sun’ Phenomenon
सुपर्णो नाम तमृषि: प्राप्तवान् पुरुषोत्तमात् । तपसा वै सुतप्तेन दमेन नियमेन च,सुपर्ण नामक ऋषिने इन्द्रियसंयम और मनोनिग्रह-पूर्वक भलीभाँति तपस्या करके भगवान् पुरुषोत्तमसे इस धर्मको प्राप्त किया
suparṇo nāma tam ṛṣiḥ prāptavān puruṣottamāt | tapasā vai sutaptena damena niyamena ca ||
ヴァイシャンパーヤナは語った。「スパルナ（Suparṇa）という名の聖仙は、至上の御方プルショーत्तマ（Puruṣottama）よりそのダルマを得た。彼は厳しい苦行（tapas）をよく修め、さらに自制（dama）と規律ある戒行（niyama）を伴って成就したのである。」
वैशम्पायन उवाच
Educational Q&A
Dharma is authentically attained through disciplined spiritual practice—tapas supported by dama (sense-restraint) and niyama (regulated conduct). The verse presents inner mastery as the ethical foundation for receiving higher teaching from the Supreme.
Vaiśampāyana reports an exemplum: the sage Suparṇa received a particular dharma/teaching from Puruṣottama, and the means of attainment is specified—intense austerity together with restraint and observance—thereby validating the teaching’s authority and the required qualifications.
