Bhagavad Gita: Chapter 2, Verse 37

हतो वा प्राप्स्यसि स्वर्ग जित्वा वा भोक्ष्यसे महीम् ।
तस्मादुत्तिष्ठ कौन्तेय युद्धाय कृतनिश्चयः ॥ २-३७ ॥

hato vā prāpsyasi svargaṁ jitvā vā bhokṣyase mahīm
tasmād uttiṣṭha kaunteya yuddhāya kṛta-niścayaḥ 2.37

Either you will be killed on the battlefield and attain the heavenly planets, or you will conquer and enjoy the earthly kingdom. Therefore, O son of Kuntī, arise with determination and fight.
