Mahabharata Drona Parva Chapter 145:6

Mahabharata Drona Parva (Jayadratha-Vadha Parva) Chapter 145:6 The father of Jayadratha is Vriddhakshatra known all over the world. It was after a long time that he got Jayadratha, that slayer of foes, for his son. (At the birth of the son) an incorporeal and invisible voice, deep as that of the clouds or of the drum, said unto king Vriddhakshatra. 'This thy son, O lord, amongst men in this world will become worthy of the two races (viz., the Solar and the Lunar) in respect of blood, behaviour, self-restraint and the other attributes. He will become one of the foremost of Kshatriyas, and will always be worshipped by heroes. But while struggling in battle, some bull among the Kshatriyas, some conspicuous person in the world, excited with wrath, will cut off this one's head.' That chastiser of foes, viz., the (old) ruler of the Sindhus, hearing these words, reflected for sometime. Overwhelmed with affection for his son, he summoned all his kinsmen and said, 'That man who will cause the head of my son to fall on the earth while the latter, struggling in battle, will be bearing a great burthen, I say that the head of that man will certainly crack into a hundred pieces.' Having spoken these words and installed Jayadratha on the throne, Vriddhakshatra, repairing to the woods, devoted himself to ascetic austerities. Endued with great energy, he is still engaged in the observance of the austerest of penances outside this very Samantapanchaka, O ape-bannered one! Therefore, cutting off Jayadratha's head in this dreadful battle, thou, O slayer of foes, shouldst, O Bharata, by thy fierce celestial weapon of wonderful feats, quickly throw that head decked with car-rings upon the lap of Vriddhakshatra himself, O younger brother of the son of the Wind-god! If thou fellest Jayadratha's head on the earth, thy own head, then, without doubt, will crack into a hundred fragments. Aided by thy celestial weapon, do thee deed in such a way that the lord of earth viz., the old Sindhu king, may not know that it is done. Truly, O Arjuna, there is nothing in the three worlds which thou canst not achieve or do, O son of Vasava!" Hearing these words (of Krishna), Dhananjaya, licking the corners of his mouth, quickly shot that arrow which he had taken up for Jayadratha's slaughter, that arrow, viz., whose touch resembled that of Indra's thunder, which was inspired with mantras and converted into a celestial weapon, which was capable of bearing any strain, and which had always been worshipped with incense and garlands. That shaft, sped from Gandiva, coursing swiftly, snatched Jayadratha's head away, like a hawk snatching away a smaller bird from the top of a tree. Dhananjaya, then, with his shafts, sent that head along in the welkin (without allowing it to fall down).
