The Vaiṣṇava, or one who has taken shelter of the Supreme Personality of Godhead, Viṣṇu, should observe the rules and regulations found in the Pañcarātra and other revealed scriptures. According to his own natural qualities and work, he should follow the code of varṇāśrama in a spirit free from motivation. The so-called knowledge received through one’s material senses, mind and intelligence is as useless as the dreams experienced by a sleeping person attached to sense gratification. Therefore, one should give up work performed for sense gratification and accept work as a matter of duty. When one has come to understand something of the truth of the self, he should give up material work performed out of duty and simply engage himself in the service of the bona fide spiritual master, who is the manifest representative of the Personality of Godhead. The servant of the spiritual master should have very firm affection for his guru, should be anxious to receive from him knowledge of the Absolute Truth, and should be devoid of envy and the tendency to talk nonsense. The soul is distinct from the gross and subtle material bodies. The spirit soul who has entered into the material body accepts bodily functions according to the reactions of his own past activities. Therefore, only the bona fide, transcendental spiritual master is capable of demonstrating pure knowledge of the self.
