Srimad Bhagavatam Canto 10, Chapter 18, Text 28

SB 10.18.28

athagata-smrtir abhayo ripum balo
 vihaya sartham iva harantam atmanah
rusahanac chirasi drdhena mustina
 suradhipo girim iva vajra-ramhasa
 
Translation: 
 
Remembering the actual situation, the fearless Balarama understood that the demon was trying to kidnap Him and take Him away from His companions. The Lord then became furious and struck the demon’s head with His hard fist, just as Indra, the king of the demigods, strikes a mountain with his thunderbolt weapon.
 
Purport: 
 
Lord Balarama’s powerful fist came crashing down upon the demon’s head, just as a huge lightning bolt comes crashing into a mountain, cracking its stone surface into pieces. The words vihaya sartham iva may also be divided vihayasa artham iva, meaning that the demon was flying in the sky on the cosmic path, vihayas, with the purpose of carrying off Balarama, who was his artham, or object of pursuit.
