"But, as Scarecrow said, it is confusing to read all those different ideas about things?" said the Lion. "It can be," said the Tin Woodman. "But whatever we read, we must learn to discern deep within ourselves what is true and what is not true, and then to ask the Great Wizard's guidance for the ultimate answers. After all; if he knows all Truth, he is going to guide us to it if we ask him. But he won't force it on us." "How do we know if he can hear us, or even that he exists if no one has seen him?" the Lion said. "Well," interceded the Tin Woodman, "from all that I've read, people throughout history have heard him speak. But to be able to hear him, we have to go into a very quiet state within ourselves every day, and learn to communicate with him." "How do we do that?" asked the Lion, still recalling the traditional tale of Lurline. "Well, I've been doing it for some time," said the Tin Woodman, "and although I haven't actually heard a voice yet, I often receive answers to my questions in symbolic form, which I am told is the language of the soul." "Can you describe it to us?" said the Lion. "Of course," said the Tin Woodman. "But you know, we have talked here for a long time. We really must get underway if we are to accomplish our mission. I'll tell you what happened when we get to Colorland. We'll stay overnight in the Yellow Belt and I'll explain everything." "Why the Yellow Belt?" asked Dorothy. "Well, the color vibration of yellow is very conductive to learning. The Winkies always subconsciously knew this. In fact, when you take a test at school, be sure to wear yellow and you'll do very well on your test." "Really?" said Dorothy. "I must remember that." "Now then, everybody up," said the Lion. "Let's be on our way. We can take the Girrephalumps as far as Octapongland. After that we'll have to walk." With that, the Girrephalumps sat down so everyone could climb aboard. The leading Girrephalump, who belonged to Dorothy, turned his head to her as she climbed aboard and said, "Forgive me if I don't talk, but I have a sore throat. Mind you, none of us care to talk much," he continued. "We have such long and delicate throats that we have to take the utmost care that we don't overdo things." "That's quite all right," replied Dorothy. "I do hope you feel better soon." "Oh, I shall. Don't worry," said the Girrephalump. "When I return from this trip, I will take a short vacation. I can't take too long or I'll get too far behind with my other work." "What other work do you do?" asked Dorothy. "Well," said the Girrephalump, "as I told you before, besides being part of the main transportation system in Oz, we are required to change the streetlight bulbs when they burn out, and to keep all the upstairs windows clean. If we get too far behind, people can't see out of their upstairs windows in the daytime; and when they're out at night they can't see what they're doing, so it's important work that we do."
