This vow has been taken for establishing righteousness. Where there are the Vedas, truth, self-control, purity, righteousness, humility, prosperity, wisdom and forbearance, there I am also to be found. You need not now be at all anxious about the slaughter of Karna.
कार्यः धर्मसंस्थापनार्थं हि प्रतिज्ञैषा ममाव्यया। ब्रह्म सत्यं दमः शौचं धर्मो ह्रीः श्रीकृतिः क्षमा॥ यत्र तत्र रमे नित्यमहं सत्येन ते शपे। न विषादस्त्वया कर्ण वैकर्तनं प्रति॥
