Fire

Yudhistira  Said
 
Karna also of the Suta caste is a mighty warrior versed in celestial weapons. In respect of the impetus of his weapons, he is endued with the strength of the Wind-god. Himself like a flame of fire, 

1. the arrows (proceeding from him) constitute its tongues. 
2. The slaps of his left hand cased in leathern fence constitute the crackling of that flame. 
3. The dust of the battle-field is its smoke. 

Urged by the sons of Dhritarashtra even as the wind urgeth the fire, Karna like unto the all-consuming fire at the end of the Yuga that is sent by Death himself, will, without doubt, consume my troops like unto a heap of straw.
