Mahabharata Sauptika Parva Chapter 4:2

Mahabharata Sauptika Parva Chapter 4:2 Any one of these, singly would destroy sleep. How great is the grief of that person whose heart is always thinking of the slaughter of his sire! My heart is now burning day and night. I fail to obtain peace. The way in which my sire in particular was slain by those sinful wretches hath been witnessed by you all. The thought of that slaughter is cutting all my vitals. How could a person like me live for even a moment after hearing the Pancalas say that they have slain my father? I cannot bear the thought of supporting life without having slain Dhrishtadyumna in battle. In consequence of the slaughter of my father he hath become slayable by me, as also all with whom he is united. Who is there so hard-hearted that would not burn after having heard the lamentations that I have heard of the king lying with broken thighs? Who is there so destitute of compassion whose eyes would not be filled with tears after hearing such words uttered by the king with broken thighs? They whose side was adopted by me have been vanquished. The thought of this enhances my sorrow as a rush of waters enhances the sea. Protected as they are by Vasudeva and Arjuna, I regard them, O uncle, to be irresistible by the great Indra himself. I am unable to restrain this rising wrath in my heart. I do not behold the man in this world that can assuage this wrath of mine! The messengers informed me of the defeat of my friends and the victory of the Pandavas. That is burning my heart. Having however, caused a slaughter of my enemies during their sleep, I shall then take rest and shall then sleep without anxiety.
