Savant Uddhava, the son of Yadava’s minister Brihaspati was an intimate friend of Lord Krishna. Only he had the permission to enter Lord’s sanctum. Seeing his friend Krishna in remorse, Uddhava asked: “Mathuranath, you seem to be upset. What is troubling you?” Lord Krishna replied: “Uddhava, I feel perplexed. I remember my days in Vrindavana. Please go to Vrindavana and get the news regarding Gopis there. Also give them my message.” Thus Lord Krishna donned Uddhava in his attire and sent him to Vraj in his chariot.
There he stayed at Nand’s home. At night, Uddhava enquired about Nand and Yashoda’s well being and about Vraj in general. That whole might passed in chatting.
