धर्मस्य बहुद्वारत्वम् — Nārada’s Audience with Indra (Śānti-parva 340)
द्वापरस्य कलेश्रैव संधौ पार्यवसानिके
dvāparasya kaleś caiva sandhau pāryavasānike
Bhīṣma disse: “Na junção conclusiva — no derradeiro fim — da era Dvāpara e no início da era Kali…”
(भीष्म उवाच
The verse frames Bhīṣma’s instruction within the yuga-transition (Dvāpara to Kali), implying that ethical guidance is especially urgent when society stands at a turning point where dharma diminishes and confusion about right conduct increases.
Bhīṣma, instructing in Śānti Parva, situates his discourse in the ‘sandhi’—the concluding boundary of Dvāpara and the beginning of Kali—preparing the listener for teachings relevant to an age of decline.
