Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The Supreme Personality of Godhead, Krsna, with the cooperation of Sankarsana, Balarama, performed activities beyond the mental comprehension of even such personalities as Lord Brahma and Lord Siva. [For instance, Krsna arranged the Battle of Kuruksetra to kill many demons for the relief of the entire world.]
