क्लैब्यं मा स्म गम: पार्थ नैतत्त्वय्युपपद्यते
क्षुद्रं हृदयदौर्बल्यं त्यक्त्वोत्तिष्ठ परन्तप

klaibyaṃ mā sma gama: pārtha naitattvayyupapadyate
kṣudraṃ hṛdayadaurbalyaṃ tyaktvottiṣṭha parantapa

Yield not, O Partha, to feebleness. It does not befit you. Cast off this petty faint-heartedness. Wake up, O vanquisher of foes!

Bhagavad Gita: Chapter 2, Verse 3
