Mbh 7.146.2b

Alas, these words of the truth-telling Vidura have come to be true. It is for him that I behold my preceptor today lying on a bed of arrows. Fie on the practices of Kshatriya! Fie on my might and prowess! Who else like me would fight with a Brahmana that is besides his preceptor? Kripa is the son of a Rishi; he is, again, my preceptor; he is also the dear friend of Drona. Alas, he lieth stretched on the terrace of his car, afflicted with my arrows. Though not wishing it, I have still been the means of crushing him with my shafts. Lying senseless on the terrace of his car, he paineth my heart exceedingly. Even though he afflicted me with shafts, I should still have only looked at that warrior of dazzling splendour (without striking him in return). Struck with numerous shafts of mine, he hath gone the way of all creatures. By that he hath pained me more than even the slaughter of my own son. Behold, O Krishna, to what plight he hath been reduced, thus lying miserably and in a senseless state on his own car. Those bulls among men that give desirable objects unto their preceptors after obtaining knowledge from them, attain to godhead. Those lowest of mortals on the other hand, who, after obtaining knowledge from their preceptors strike the latter, those wicked men, go to hell. Without doubt, this act that I have done will lead me to hell. I have deeply pierced my preceptor on his car with showers of arrows. While studying the science of arms at his feet, Kripa told me in those days, ‘Do not, O thou of Kuru’s race, ever strike thy preceptor.’ That command of my righteous and high-souled preceptor I have not obeyed, for I have struck, the very Kripa himself with my shafts. I bow to that worshipful son of Gotama, to that unretreating hero. Fie on me, O thou of Vrishni’s race, since I have struck even him.” While Savyasachin was thus lamenting for Kripa, the son of Radha, beholding the ruler of the Sindhu slain, rushed towards him.
