kṛtvaiva karmāṇi mahānti śūrāstapodamācāravihāraśīlāḥ |
devānṛṣīnpretagaṇāṃśca sarvānsaṃtarpayitvā vidhinā pareṇa || 40 ||

Ye, who are so valiant, and engaged in asceticism, self-restraining exercises, and religious ordinances, and fond of exertion, after having performed great deeds and gratified the gods and Rishis and the Pitris, ye will at last in due course attain by your own acts the supreme region--the abode of all virtuous men! O ornament of Kuru's race, may no doubts cross thy mind on account of these thy sufferings, for this affliction is for thy good!"
