Bhagavad Gita 2.37

हतो वा प्राप्स्यसि स्वर्गं जित्वा वा भोक्ष्यसे महीम |
तस्मादुतिष्ठ कौन्तेय युद्धाय कृतनिश्चय:

Translation

If you fight, you will either be slain on the battlefield and go to the celestial abodes, or you will gain victory and enjoy the kingdom on earth. Therefore arise with determination, O son of Kunti, and be prepared to fight.
