Nectar of Instruction
...In all spiritual affairs, one’s first duty is to control his mind and senses. Unless one controls his mind and senses, one cannot make any advancement in spiritual life. Everyone within this material world is engrossed in the modes of passion and ignorance. One must promote himself to the platform of goodness, sattva-guna, by following the instructions of Rupa Gosvami, and then everything concerning how to make further progress will be revealed. ...Then it will be easier to make one’s life successful. Hare Krishna.
