Vṛtra’s Cosmic Threat, Viṣṇu’s Upāya, and the Conditional Vulnerability
Udyoga-parva 10
न शुष्केण न चार्द्रेण नाश्मना न च दारुणा । न शस्त्रेण न चास्त्रेण न दिवा न तथा निशि
na śuṣkeṇa na cārdreṇa nāśmanā na ca dāruṇā | na śastreṇa na cāstreṇa na divā na tathā niśi |
Śalya declares a condition of invulnerability: he is not to be slain by anything dry or wet, nor by stone or wood, nor by hand-held weapons or missiles, nor by day nor by night. Framed as a bargain for perpetual alliance with Indra and the gods, the statement reflects a strategic, ethically charged attempt to secure safety through carefully worded terms.
शल्य उवाच
The verse highlights how power can be sought through narrowly defined protections and contracts; ethically, it warns that relying on technical conditions rather than righteous conduct (dharma) often leads to vulnerability through unforeseen exceptions.
Śalya articulates a set of exclusions—dry/wet, stone/wood, weapon/missile, day/night—as the terms under which he would accept an enduring alliance (sāndhi) with Indra and the gods, presenting a classic epic motif of conditional invulnerability.
