The question asks for the comparisons made for Uddhav's behavior. Based on the provided text from Pad 3 of Surdas's Bhramargeet, the gopis use three distinct comparisons to criticize Uddhav and his yogic teachings. First, they compare his yoga teachings to a 'bitter gourd' (कड़वी ककड़ी) to show its unpalatable nature. Second, they compare him to an incompetent 'doctor/vaidya' (वैद्य) who prescribes medicine without examining the patient, highlighting that Uddhav gives advice without understanding their pain. Third, they compare him to a 'snake' (साँप), indicating that his presence and teachings are harmful/poisonous to those already suffering in the agony of separation.
