इत्येवमुक्ते वचने ततो5गस्त्य: प्रतापवान्
ity evam ukte vacane tato 'gastyaḥ pratāpavān
Vaiśampāyana said: When these words had thus been spoken, then the mighty sage Agastya—renowned for his spiritual power and heroic energy—(responded/acted accordingly).
वैशम्पायन उवाच
The verse functions as a narrative hinge: it highlights that speech has consequences and that a figure of recognized moral and spiritual authority (Agastya) responds after hearing what was said, underscoring attentive listening and responsible action following counsel.
Vaiśampāyana marks the end of a preceding statement ('thus, when these words were spoken') and transitions to Agastya, describing him as 'pratāpavān' (mighty), preparing the listener for Agastya’s ensuing reply or deed.
