Bhagavad Gita 2.37 — Rise with resolve
हतो वा प्राप्स्यसि स्वर्गं जित्वा वा भोक्ष्यसे महीम्। तस्मादुत्तिष्ठ कौन्तेय युद्धाय कृतनिश्चयः ॥
hato vā prāpsyasi svargaṃ jitvā vā bhokṣyase mahīm | tasmāduttiṣṭha kaunteya yuddhāya kṛtaniścayaḥ ||
Meaning
If you are killed, you will reach heaven; if you win, you will enjoy the earth. So rise, son of Kunti, determined to fight.
