yatra saṃkṣayamāyāti sarvaṃ tatrāśubhaṃ kṛtam ..
tatra yo vṛṣabhaṃ dadyādbrāhmaṇāya nṛpottama ..
tadromasaṃkhyayāsvarge sa pumānvasati dhruvam ..41..

Where all the inauspicious deeds committed are completely destroyed, / he who gives a bull to a brahmin there, O best of kings, / that person dwells in heaven for as many years as the hairs on that [bull], assuredly. (41)
