Bhagavad Gita · 1.32

किं नो राज्येन गोविन्द किं भोगैर्जीवितेन वा।येषामर्थे काङ्क्षितं नो राज्यं भोगाः सुखानि च॥

kiṁ no rājyena govinda kiṁ bhogair jīvitena vā yeṣhām arthe kāṅkṣhitaṁ no rājyaṁ bhogāḥ sukhāni cha

O Govinda, of what use is a kingdom to us, or enjoyments, or even life itself? The very people for whose sake we desire kingdom, enjoyments, and pleasures are standing here in battle, ready to give up their lives and wealth.
