श्रीभगवानुवाचकुतस्त्वा कश्मलमिदं विषमे समुपस्थितम्।अनार्यजुष्टमस्वर्ग्यमकीर्तिकरमर्जुन॥

śhrī bhagavān uvācha kutas tvā kaśhmalam idaṁ viṣhame samupasthitam anārya-juṣhṭam asvargyam akīrti-karam arjuna

The Supreme Lord said: From where has this dejection come upon you at this critical hour? It is not befitting an honorable person; it leads not to heaven, but to disgrace, O Arjuna.
