We have got four defects — means we commit mistake, we become illusioned or bewildered, our senses are imperfect, and, because everything is imperfect, still we want to become teacher, that is cheating. I am imperfect. How can I teach? That is going on. A imperfect person is teaching about transcendental knowledge. Therefore people are being cheated. Our process is to take lesson from the perfect person and distribute it, just we are doing. Krsna consciousness movement means we are preaching what Krsna has said, that’s all. Not that we have manufactured something new. No. That is not our business. How I can manufacture? I am imperfect. How can I manufacture? But the spiritual master who follows the perfect teacher, he is perfect. He is perfect because whatever he is speaking, that is the statement of the perfect person.
