sah labdha-samjñah punar utthito rusa

 vyadaya kesi tarasapatad dharim

so ’py asya vaktre bhujam uttaram smayan

 pravesayam asa yathoragam bile

 

Translation: 

 

Upon regaining consciousness Kesi angrily got up, opened his mouth wide and again rushed to attack Lord Krsna. But the Lord just smiled and thrust His left arm into the horse’s mouth as easily as one would make a snake enter a hole in the ground.
