Vāsudeva’s Upadeśa: The Inner Enemy and the Indra–Vṛtra Precedent (आत्मशत्रु-बोधः; इन्द्र-वृत्रोपाख्यानम्)
व्याप्ते ज्योतिषि वृत्रेण रूपेडथ विषये हते
vyāpte jyotiṣi vṛtreṇa rūpeḍatha viṣaye hate
Vāyu said: “When the luminous realm had been pervaded by Vṛtra, and when he was then slain within the sphere of manifestation, the order of the worlds was restored.”
वायुदेव उवाच
The verse frames the slaying of Vṛtra as more than a battle: it is the removal of an obstruction that had overwhelmed the luminous order. Ethically, it presents rightful force as that which restores balance and protects the world’s proper functioning.
Vāyu recalls a moment when Vṛtra had spread over the realm of light (jyotis). After Vṛtra is killed within the ‘sphere’ (viṣaya), the implication is that the blockage is cleared and the cosmic situation returns to order.
