Bhagavad Gita
1.16

अनन्तविजयं राजा कुन्तीपुत्रो युधिष्ठिरः | नकुलः सहदेवश्च सुघोषमणिपुष्पकौ ||१६||

anantavijayaṁ rājā kuntī-putro yudhiṣṭhiraḥ nakulaḥ sahadevaśh cha sughoṣa-maṇipuṣhpakau

Translation

King Yudhishthira, the son of Kunti, blew his conchshell Anantavijaya; Nakula and Sahadeva blew their conchshells, Sughosa and Manipushpaka.

Interpretation

Yudhishthira's conch is called 'Anantavijaya' — 'eternal victory.' The name itself is a statement of confidence in the righteousness of their cause. Every conch on the Pandava side seems to carry prophetic significance.
