kaleraṃśāttu saṃjajñe bhuvi duryodhano nṛpaḥ |

He who was known as Dhritarashtra born of the seed of Krishna-Dwaipayana, and gifted with long arms and great energy, also a monarch, of the prophetic eye, became blind in consequence of the fault of his mother and the wrath of the Rishi. His younger brother who was possessed of great strength and was really a great being known as Pandu, devoted to truth and virtue, was Purity's self. And, O king, thou shouldst know that he who was known on earth as Vidura, who was the first of all virtuous men, who was the god of Justice himself, was the excellent and greatly fortunate son of the Rishi Atri. The evil-minded and wicked king Duryodhana, the destroyer of the fair fame of the Kurus, was born of a portion of Kali on earth. He it was who caused all creatures to be slain and the earth to be wasted; and he it was who fanned the flame of hostility that ultimately consumed all. They who had been the sons of Pulastya (the Rakshasas) were born on earth among men of Duryodhana's brothers, that century of wicked individuals commencing with Duhasasana as their first. And, O bull among the Bharata princes, Durmukha, Duhsaha, and others whose names I do not mention, who always supported Duryodhana (in all his schemes), were, indeed, the sons of Pulastya. And over and above these hundred, Dhritarashtra had one son named Yuyutsu born of a Vaisya wife.'
