Nahūṣa’s Fall Explained: Agastya’s Account to Indra (Śalya-narrated)
एते प्रमाणं भवत उताहो नेति वासव । नहुषो नेति तानाह तमसा मूढचेतन:
ete pramāṇaṃ bhavata utāho neti vāsava | nahuṣo neti tān āha tamasā mūḍha-cetanaḥ ||
Śalya said: “Those sages asked, ‘O Vāsava (Indra), do you accept these Vedic mantras—prescribed for the purificatory sprinkling of cows—as authoritative (pramāṇa), or not?’” Nahuṣa, his mind deluded by darkness (tamas), replied, “No,” thus rejecting the authority of the Vedic mantras.
शल्य उवाच
The verse warns that when a person—especially a ruler—falls into tamas (spiritual and moral ignorance), he may reject pramāṇa (legitimate authority such as Vedic injunctions). Such denial of sacred and ethical norms signals a collapse of dharma and becomes a cause of downfall.
Sages question Nahuṣa (addressed as Vāsava/Indra due to his assumed position) about whether he accepts certain Vedic mantras as authoritative. Nahuṣa, mentally clouded by tamas, answers ‘no,’ explicitly refusing their authority.
