hato vā prāpsyasi svargaḿ
jitvā vā bhokṣyase mahīm
tasmād uttiṣṭha kaunteya
yuddhāya kṛta-niścayaḥ
hataḥ — being killed; vā — either; prāpsyasi — you gain; svargam — the heavenly kingdom; jitvā — by conquering; vā — or; bhokṣyase — you enjoy; mahīm — the world; tasmāt — therefore; uttiṣṭha — get up; kaunteya — O son of Kuntī; yuddhāya — to fight; kṛta — determined; niścayaḥ — in certainty.
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.
