Mbh 7.49.1a

“Sanjaya said, ‘After the slaughter of that hero, that leader of car-divisions, viz., the son of Subhadra, the Pandava warriors, leaving their cars and putting off their armour, and throwing aside their bows, sat, surrounding king Yudhishthira. And they were brooding over that grief of theirs, their hearts fixed upon the (deceased) Abhimanyu. Indeed, upon the fall of that heroic nephew of his, viz., the mighty car-warrior Abhimanyu, king Yudhishthira, overwhelmed with grief, indulged in (these) lamentations: “Alas, Abhimanyu, from desire of achieving my good, pierced the array formed by Drona and teeming with his soldiers. Encountering him in battle, mighty bowmen endued with great courage, accomplished in weapons and incapable of being easily defeated in battle, were routed and forced to retreat. Encountering our implacable foe Duhsasana in battle, he with his arrows, caused that warrior to fly away from the field, deprived of his senses. Alas, the heroic son of Arjuna, having crossed the vast sea of Drona’s army, was ultimately obliged to become a guest of Yama’s abode, upon encountering the son of Duhsasana. When Abhimanyu is slain, how shall I cast my eyes on Arjuna and also the blessed Subhadra deprived of her favourite son? What senseless, disjointed, and improper words shall we have to say today unto Hrishikesa and Dhananjaya! Desirous of achieving what is good, and expectant of victory, it is I who have done this great evil unto Subhadra and Kesava and Arjuna. He that is covetous never beholdeth his faults. Covetousness spring from folly. Collectors of honey see not the fall that is before them; I am even like them. He who was only a child, he who should have been provided with (good) food, with vehicles, with beds, with ornaments, alas, even he was placed by us in the van of battle. How could good come to a child of tender years, unskilled in battle, in such a situation of great danger.
