If you want real Guru, they should be disciplic succession of madavacharya, ramanujacharys, Visnuswami, Nimarakacharya. Then these guru should teach you to surrender to GOVINDA. Many of us make a guru to some Siddha babji , because they would have got some material gain from him sometime. One should remember they are not the body, they are spiritual soul . Your soul should get benefit from guru to get love of Krishna. All material benifit are useless and temporary for this life time. But once you get the love of Krishna it remains forever and goes to you in every life.
