Srila Visvanatha Cakravarti has written an extensive purport to this verse, elaborately analyzing this portion of Lord Krishna's pastimes. Just as a man places his valuable gold within fire to reveal its purity, the Lord placed His most beloved devotees, the residents of Vrindavana, in the fire of separation from Him in order to manifest their supreme love. This is the essence of Acarya Visvanatha's comments.
