Bhagavad Gita · 1.31

न च श्रेयोऽनुपश्यामि हत्वा स्वजनमाहवे।न काङ्क्षे विजयं कृष्ण न च राज्यं सुखानि च॥

na cha śhreyo 'nupaśhyāmi hatvā sva-janam āhave na kāṅkṣhe vijayaṁ kṛṣhṇa na cha rājyaṁ sukhāni cha

I do not see how any good can come from killing my own kinsmen in this battle. O Krishna, I desire neither victory, nor kingdom, nor pleasures.
