Translation: 

 

Kesi’s teeth immediately fell out when they touched the Supreme Lord’s arm, which to the demon felt as hot as molten iron. Within Kesi’s body the Supreme Personality’s arm then expanded greatly, like a diseased stomach swelling because of neglect.

 

Purport: 

 

Srila Visvanatha Cakravarti points out that although Lord Krsna’s arm is more tender and cooling than a blue lotus, to Kesi it felt extremely hot as if made of lightning bolts.
