paritranaya sadhunam vinasaya ca duskrtam [Bg. 4.8]. The mission of Lord Krsna was performed on the Battlefield of Kuruksetra, for by the Lords mercy Arjuna was victorious due to being a great devotee whereas the others were killed simply by the Lords 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 Lords instructions in the form of Bhagavad-gita are full of jnana and vairagya, knowledge and renunciation. In the human form of life, one must learn these two thingshow to become detached from the material world and how to acquire full knowledge in spiritual life. This is the Lords mission (paritranaya sadhunam vinasaya ca duskrtam [Bg. 4.8]). After executing His complete mission, the Lord returned to His home, Goloka Vrndavana.
