Puṣṭa Kṛṣṇa: "The best change can be effected only by hearing from authoritative sources. The best example is here."
Prabhupāda: This is the authoritative source says: that you are not master, you are servant. Cultivate this knowledge. Don't try to become a master, falsely. That will never be successful. Remain servant of Kṛṣṇa, you'll be happy. That is the business of spiritual master. He gives the right information; therefore he is respected so much, because he does not cheat. "Yes, you can become master, even God you can become"—this is cheating. The real spiritual master says that "You can never become master. You are always servant." And therefore he's worshiped. He gives the right information. Therefore he is honored so, because he does not cheat. The so-called spiritual master is cheating, that "You take this mantra and give me some money and you become God." This cheating is going on. Spiritual master is to be worshiped. Why? Because he does not cheat. He gives the right information. That is his credit. Guruṣu nara-mati (Padma Purāṇa). Therefore one should not take guru as ordinary human being. Ordinary human being, he'll cheat you, or he'll give some information, he's cheating. But a guru, real guru, he'll not cheat you. Therefore he should be worshiped as good . . . God does not cheat you. Therefore guru should not be taken as ordinary human being. Guruṣu nara-mati. "I see that he is like ordinary man. His son is calling him 'father.' His wife is . . ." That's all right, but because he's giving the right information, he is not ordinary human being. Therefore he should be worshiped as good as God. He does not cheat. That is the test of guru. He'll never say that "You give me some bribe and you'll become God by meditation, transcendental." He'll never say that. This is cheating. Why father is respected? Because he never cheats the son. Father is also a man, another man. Why father is . . .? Because he's always wishing welfare of the son; he does not cheat, sincerely teaches him the reality. Then?
Puṣṭa Kṛṣṇa: "Arjuna is hearing the science of God from Kṛṣṇa. The living entity, if he submits to this hearing process, will lose his long-cherished desire to dominate material nature, and gradually and proportionately as he reduces his long desire to dominate, he comes to enjoy spiritual happiness. In a Vedic mantra it is said that as he becomes learned in association with the Supreme Personality of Godhead, he proportionately relishes his eternal, blissful life."
