SB 9.24.67

prthvyah sa vai guru-bharam ksapayan kurunam
 antah-samuttha-kalina yudhi bhupa-camvah
drstya vidhuya vijaye jayam udvighosya
 procyoddhavaya ca param samagat sva-dhama
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
Thereafter, Lord Sri Krsna created a misunderstanding between family members just to diminish the burden of the world. Simply by His glance, He annihilated all the demoniac kings on the Battlefield of Kuruksetra and declared victory for Arjuna. Finally, He instructed Uddhava about transcendental life and devotion and then returned to His abode in His original form.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
Paritranaya sadhunam vinasaya ca duskrtam. The mission of Lord Krsna was performed on the Battlefield of Kuruksetra, for by the Lord’s mercy Arjuna was victorious due to being a great devotee whereas the others were killed simply by the Lord’s glance, which cleansed them of all sinful activities and enabled them to attain sarupya. Finally, Lord Krsna instructed Uddhava about the transcendental life of devotional service, and then, in due course of time, He returned to His abode. The Lord’s instructions in the form of Bhagavad-gita are full of jñana and vairagya, knowledge and renunciation. In the human form of life, one must learn these two things — how to become detached from the material world and how to acquire full knowledge in spiritual life. This is the Lord’s mission (paritranaya sadhunam vinasaya ca duskrtam). After executing His complete mission, the Lord returned to His home, Goloka Vrndavana.
Thus end the Bhaktivedanta purports of the Ninth Canto, Twenty-fourth Chapter, of the Srimad-Bhagavatam, entitled “Krsna, the Supreme Personality of Godhead.”
