1. With firm faith, work as ordered by guru,then life is successful

    We should have firm faith, niscaya.But niscayat; at the same time, you should not sit idly. You should work according to the direction of the spiritual master. "Now Krsna has given me assurance. Now let me sleep. Everything will come automatically." No. Tat-tat-karma-pravartanat [Upadesamrta 3]. The spiritual master says, "You must do this," you must do that. That is called tat-tat-karma-pravartanat. Not that "Now I am initiated and…"

    Vaisnava principle is you must act according to the order of spiritual master.  This is called vyavasayatmika buddhi. Vyavasayatmika buddhi, niscayatmika buddhi, means with good faith that "I must execute it. That is my life and soul." If we take that, then our life is successful.
