Vāsudeva’s Upadeśa: The Inner Enemy and the Indra–Vṛtra Precedent (आत्मशत्रु-बोधः; इन्द्र-वृत्रोपाख्यानम्)
आकाशे वृत्रभूते5थ शब्दे च विषये हते
ākāśe vṛtrabhūte ’tha śabde ca viṣaye hate
当虚空仿佛也被弗利陀罗所阻塞,而声音本身——连同其作用之域——亦被击倒之时,景象便陷入惊愕的寂然,宛如听觉的媒介都被压覆。
वायुदेव उवाच
The verse uses cosmic metaphor to show how overwhelming force can suspend ordinary functions (like sound and its perception), reminding the listener that human experience depends on subtle conditions that can be eclipsed by greater powers.
Vāyudeva describes a moment of extreme disturbance: the sky seems ‘Vṛtra-like’ (blocked or covered), and sound along with its perceptible range is ‘struck down,’ conveying a sudden, portentous hush amid upheaval.
