Mbh 12.27.1b

He who had protected and reared us when we were children, alas, he was caused to be slain by my sinful self that am covetous of kingdom, that am a slayer of reverend seniors, and a perfect fool, for the sake of sovereignty that would last but a few days. Our preceptor, the great archer Drona, adored by all the kings, was approached by me and addressed falsely in respect of his son. The memory of that act of mine is burning all my limbs. The preceptor said unto me, 'Tell me truly, O king, whether my son liveth still.' Expecting truth from me, the Brahmana asked me of all others. By silently uttering the word 'elephant,' I behaved falsely towards him. Sinful that I am, exceedingly covetous of kingdom, and a slayer of my reverend seniors, I behaved even thus towards my preceptor in battle, throwing off the garb of truth (which I was believed to wear), for I said unto him that Aswatthaman had been killed when, in fact, an elephant of that name had been slain. To what regions shall I go (thereafter), having perpetrated such infamous deeds? I caused also my eldest brother Karna to be slain, that terrible warrior who never retreated from battle. Who is there more sinful than I? Through covetousness I caused Abhimanyu of tender years, that hero who resembled a lion born in the hills, to penetrate into the array that was protected by Drona himself. I am like one guilty of infanticide. Sinful as I am, I have not since then, been able to look Arjuna or the lotus-eyed Krishna in the face. I grieve also for Draupadi who is bereft of her five sons like the Earth bereft of her five mountains. I am a great offender, a great sinner, and a destroyer of the earth! Without rising from this seat that I now occupy, I will weaken my body (by starvation) and meet with death. Know me who am the slayer of my preceptor as one that has sat down here in the observance of the Praya vow. An exterminator of my race, I must do so in order that I may not he reborn in any of other orders of beings!
