Text 37

हतो वा प्राप्स्यसि स्वर्गं जित्वा वा भोक्ष्यसे महीम् ।
तस्मादुत्तिष्ठ कौन्तेय युद्धाय कृतनिश्चयः ॥३७॥

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

Translation:

O son of Kunti, either you will be killed on the battlefield and attain the heavenly planets, or you will conquer and enjoy the earthly kingdom. Therefore, get up with determination and fight.

Purport:

Even though there was no certainty of victory for Arjuna's side, he still had to fight; for, even being killed there, he could be elevated into the heavenly planets.
