One should, hence, engage in work knowing that one’s purpose would be achieved by a combination of both Destiny and Exertion. He that engageth in acts under this belief is never pained by failure, nor delighted by success. This, O Bhimasena, was the intended import of my speech.

A person, when his mind is upset should not lose his cheerfulness and must yield neither to langour nor depression. It is for this that I spoke to thee in the way I did. When the morrow comes, I will go, O Pandava, to Dhritarashtra’s presence. I will strive to make peace without sacrificing your interests. If the Kauravas make peace, then boundless fame will be mine. Your purposes will be achieved, and they also will reap great benefit. If, however, the Kauravas, without listening to my words, resolve to maintain their opinion, then there will undoubtedly be a formidable war. In this war burthen resteth on thee, O Bhimasena. That burthen should also be borne by Arjuna, while other warriors should all be led by both of you. In case of war happening, I will certainly be the driver of Vibhatsu’s car, for that, indeed, is Dhananjaya’s wish and not that I myself am not desirous of fighting. It is for this that, hearing thee utter thy intention, I rekindled that thy energy, O Vrikodara.’”
