Mbh 7.145.1j

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). For grieving his foes and gladdening his friends, the son of Pandu, by shooting his shafts repeatedly at it, sent that head outside the limits of Samantapanchaka. Meanwhile, king Vriddhakshatra, the father of thy son-in-law, endued with great energy, was, O sire, engaged in his evening prayers.
