कस्यचित् त्वथ कालस्य व्यास: सत्यवतीसुत:
kasyacit tv atha kālasya vyāsaḥ satyavatīsutaḥ
Dijo Vaiśampāyana: Pasado algún tiempo, llegó Vyāsa—hijo de Satyavatī—, un momento decisivo en que un venerable sabio interviene en el curso de los acontecimientos.
वैशम्पायन उवाच
The verse foregrounds kāla (time) and the timely appearance of a great ṛṣi: in the Mahābhārata’s ethical world, decisive turns often come when time ripens and authoritative wisdom intervenes to redirect events toward dharma.
The narrator signals a transition: after an interval, Vyāsa—identified by his lineage as Satyavatī’s son—enters the scene, typically to advise, reveal hidden truths, or set in motion a consequential development.
