Śānti-parva 168: Śoka-nivṛtti-buddhi (The Cognition that Reduces Grief) and Piṅgalā’s Nairāśya
वैशमग्पायन उवाच समाप्तवचने तस्मिन्नर्थशास्त्रविशारद: । पार्थो धर्मार्थतत्त्वज्ञो जगौ वाक््यं प्रचोदित:
Vaiśaṃpāyana uvāca: samāptavacane tasminn arthaśāstraviśāradaḥ | pārtho dharmārthatattvajño jagau vākyaṃ pracoditaḥ ||
Vaiśaṃpāyana said: When that expert in statecraft had finished speaking, Pārtha—knower of the true principles of dharma and worldly welfare—was prompted to respond and spoke these words.
वैशमग्पायन उवाच
The verse frames ethical-political instruction: after a discourse by a master of arthaśāstra, Arjuna—presented as discerning both dharma (moral law) and artha (practical welfare)—is moved to speak, signaling that righteous governance requires integrating ethical principle with pragmatic policy.
Vaiśaṃpāyana narrates a transition in dialogue: an expert in statecraft finishes his speech, and Arjuna (Pārtha), prompted by the situation, begins his reply.
