Bhishma

“The Vedas that are in thy body, and the high status of Brahmana that is also in thee, and the ascetic merit thou hast earned by the severest of austerities, I do not strike at these! I strike, however, at that Kshatriyahood which thou, O Rama, hast adopted! When a Brahmana taketh up weapons, he becometh a Kshatriya. Behold now the power of my bow and the energy of my arms! Speedily shall I cut off that bow of thine with a sharp shaft!–Saying this I shot at him..
And those fierce arrows of tremendous impetus, resembling snakes, or fire, or poison, coming at me from all sides, pierced my very vitals and caused me to tremble. Summoning all my coolness then addressed myself for the encounter, and filled with rage I pierced Rama with a hundred arrows. And afflicted with those hundred blazing shafts resembling either fire, or the sun or looking like snakes of virulent poison, Rama seemed to lose his senses! Filled, O Bharata, with pity (at the sight), I stopped of my own accord and said,–Oh, fie on battle! Fie on Kshatriya practices! And overwhelmed, O king, with grief, I repeatedly said,–Alas, great is the sin committed by me through observance of Kshatriya practices, since I have afflicted with arrows my preceptor who is a Brahmana endued with a virtuous soul!–After that, O Bharata, I ceased striking Jamadagni’s son any more. At this time, the thousand-rayed luminary, having heated the earth with his rays, proceeded at the close of day to his chambers in the west and the battle also between us ceased..” – The Mahabharata, Book 5: Udyoga Parva: Uluka Dutagamana Parva: Section CLXXXII
