taṃ tu saṅkarṣaṇo mūrdhni patantam acalo yathā //

15 & 17. The wicked and powerful monkey broke the jar, tore the clothes of women, and caused infinite annoyance to Balarama; and elated with pride treated Balarama with great contempt. Considering its wicked and mischievous conduct and how it harrassed the country Balarama in a rage took up his bolt (mortar) and plough to kill the enemy: Dwivida too, being very powerful, pulled out a Sala tree (a hill) with his hand, suddenly sprang at him and dealt a blow on his head.

18—20. The powerful Sankarshana seeing that tree coming down like a hill (D. eying at the falling hill, in a rage) struck it down with his musala called Sunanda: the monkey (also) had its head split with the musala and, covered with torrents of blood, shone like a mountain covered with a solution of coloured earths: the monkey did not mind the stroke, pulled out another tree removing all its leaves by dint of his strength and with it in great rage struck Balarama.
