But now there is another question to be understood. What man knows is generally the world that he sees around himself. Very few people trouble to think that there is something beyond that which they realize around themselves. To many it is a story, when they hear that there are two worlds. But if one looks deep within oneself, there are not only two worlds, there are so many worlds that it is beyond expression. That part of one's being which is receptive is mostly closed in the average man. What he knows is to express outwardly and to receive from this same sphere as much as he can receive by himself. For instance, the difference between a simple man and a thinking person with deeper understanding is that, when the simple person has received a word only in his ears, the thinking person has received the same word as far as his mind. So the same word has reached the ears of the one, and the heart of the other. This man whose ears the word has touched has only seen the word, but he whose heart the word has touched has seen deeper.
