The Great Epic of the Bhārata dynasty 8.57.49

8.57.49

ubhau hi śūrau kṛtinau dṛḍhāstrau mahārathau saṃhananopapannau |
etādṛśau phalgunavāsudevau ko'nyaḥ pratīyānmadṛte nu śalya || 49 ||

Even such are Vasudeva, and the son of Pandu. Indeed, the mountains of Himavat may move from the spot where they stand but not the two Krishnas. Both of them are heroes, possessed of great skill, firm in the use of weapons, and mighty car-warriors. Both of them have adamantine frames. Who else, O Shalya, save myself, would proceed against Phalguna and Vasudeva that are even such? The desire cherished by me today, viz., that of a battle with the son of Pandu, O ruler of the Madras, will be fulfilled without delay. Soon will that wonderful and matchless and beautiful battle take place. Either I will overthrow those two in battle today, or the two Krishnas will today overthrow me." Saying these words unto Shalya, Karna, that slayer of foes, began to utter loud roars in that battle, like those of the clouds.
