saṃgamya sūtaputreṇa karṇenāhavaśobhinā |
duryodhanaḥ priye nityaṃ vartamāno mahīpatiḥ |

"Meanwhile the royal son of Dhritarashtra began to rule the earth, along with his heroic brothers as also with Bhishma and Drona and Kripa. And with the assistance of the Suta's son crowned with martial glory, Duryodhana remained ever intent on the welfare of the rulers of the earth, and he worshipped the foremost of Brahmanas by celebrating sacrifices with profuse gifts. And that hero and subduer of foes, O king, was engaged in doing good to his brothers, concluding for certain in his mind that giving and enjoying are the only use of riches."
