Bhishma Parva 121.51

Eating into my very vitals, and penetrating even through my invulnerable armour, these arrows are striking like so many bludgeons. Surely they are not Shikhandin's. Of the touch like that of a Brahmana's rod, of velocity like that of the thunder bolt and incapable of being repulsed, these arrows are sucking out my vital energies. Surely they are not Shikhandin's.
