Mahabharata Drona Parva Chapter 182:3

Mahabharata Drona Parva (Ghatotkacha-badha Parva) Chapter 182:3 Indeed, Achyuta always placed other foremost of car-warriors before Karna, thinking how that fatal dart of ours might be made fruitless by ourselves, O lord! When, again, the high-souled Krishna protected Partha in this manner from Karna, why, O monarch, would not that foremost of beings protect his own self? Reflecting well, I see that there is no person in the three worlds who is able to vanquish that chastiser of foes, viz., Janardana, that hero bearing the discus in hand. Sanjaya continued, 'That tiger among car-warriors, viz., Satyaki of prowess incapable of being baffled, asked the mighty-armed Krishna about the great car-warrior, Karna, saying, "O Janardana, even this had been Karna's firm resolution, viz., that he would hurl that dart of immeasurable energy at Phalguna. Why, however, did not the Suta's son actually hurl it then at him? Vasudeva said, "Duhsasana and Karna and Sakuni and the ruler of the Sindhus, with Duryodhana at their head, had frequently debated on this subject. Addressing Karna, they used to say, 'O Karna. O great bowman, O thou of immeasurable prowess in battle, O foremost of all victors, this dart should not be hurled at any one else than that great car-warrior, viz., Kunti's son, Partha or Dhananjaya. He is the most celebrated amongst them, like Vasava amongst the gods. He being slain, all the other Pandavas with the Srinjayas will be heartless like fireless celestials! Karna having assented to this, saying 'So be it' (the desire of) slaughtering the wielder of Gandiva, O bull amongst the Sinis, was ever present in Karna's heart. I, however, O foremost of warriors, always used to stupefy the son of Radha. It was for this that he did not hurl the dart at Pandu's son, owning white steeds. As long as I could not baffle that means of Phalguna's death, I had neither sleep, nor joy in my heart, O foremost of warriors! Beholding that dart, therefore, rendered futile through Ghatotkacha, O bull amongst the Sinis, I regarded Dhananjaya today to have been rescued from within the jaws of Death. I do not regard my sire, my mother, yourselves, my brothers, ay, my very life, so worthy of protection as Vibhatsu in battle. If there be anything more precious than the sovereignty of the three worlds, I do not, O Satwata, desire (to enjoy) it without Pritha's son, Dhananjaya (to share it with me). Beholding Dhananjaya, therefore, like one returned from the dead, these transports of delight, O Yuyudhana, have been mine. It was for this that I had despatched the Rakshasa unto Karna for battle. None else was capable of withstanding, in the night, Karna in battle. Sanjaya continued, 'Even thus did Devaki's son who is ever devoted to Dhananjaya's good and to what is agreeable to him, speak unto Satyaki on that occasion.
