हतो वा प्राप्स्यसि स्वर्गं जित्वा वा भोक्ष्यसे महीम्।तस्मादुत्तिष्ठ कौन्तेय युद्धाय कृतनिश्चयः॥

hato vā prāpsyasi svargaṁ jitvā vā bhokṣhyase mahīm tasmād uttiṣhṭha kaunteya yuddhāya kṛita-niśhchayaḥ

If you are killed, you will attain heaven; if you are victorious, you will enjoy the earth. Therefore, arise, O son of Kunti, resolved to fight!
