"The atman is an entity about which very few people know. Even if they are told about the atman, very few individuals can comprehend its nature. Extremely rare are individuals who can teach about the atman or learn about it. rare is the skilled teacher and rarer still the student who know about the atman."
"There are ignorant ones who think they can teach about the atman. They have not been able to comprehend the nature of the atman. The atman appears to them in different forms, the only learned instructor is one who knows no difference between the atman and the universe. He alone is capable of dispelling all doubt. The atman may be proved to be as small as an atom. But, in reality it is smaller still. The atman is actually beyond all debate."
