-First tab
There had been no mention of such an inscription in the Neverending Story. Could it be that Atreyu hadn’t noticed it? But that didn’t matter now. What mattered was that the words gave him permission, ordered him in fact, to do whatever he pleased. Bastian approached the wall of luminous plants to see if he could slip through somewhere. To his delight he found that the wall could easily be thrust aside like a curtain. Out he stepped. In the meantime, the night plants had kept on growing, gently but irresistibly, and Perilin had become a forest such as no human eye had ever beheld. The great trunks were now as high and thick as church towers, and still growing. In places these shimmering, milky-white pillars were so close together that it was impossible to pass between them. And seeds were still falling like a shower of sparks. On his way through the luminous forest, Bastian tried hard not to step on the glittering seeds that lay on the ground, but this soon proved impossible. There simply wasn’t a foot’s breadth of ground from which nothing was sprouting. So he stopped worrying and went wherever the giant trees left a path open for him.
-Second tab
Bastian was delighted at being handsome. It didn’t bother him that there was no one to admire him. On the contrary, he was glad to have the pleasure all to himself. He didn’t care a fig for being admired by the lugs who had always made fun of him. If he thought of them at all, it was almost with pity. In this forest, where there were no seasons and no alternation of day and night, the feeling of time was entirely different from anything Bastian had ever known. He had no idea how long he had been on his way. But little by little his pleasure in being handsome underwent a change. He began to take it for granted. Not that he was any less happy about it; but now he had the feeling that he had never been any different. For this there was a reason which Bastian was not to discover until much later. The beauty that had been bestowed on him made him forget, little by little, that he had ever been fat and bowlegged.
-Third tab
While going deeper and deeper into the Night Forest, he began to feel hungry. He picked off a few of the strangely shaped luminous fruits and nibbled gingerly to see if they were edible. Edible was no word for it; some were tart, some sweet, some slightly bitter, but all were delicious. He ate as he walked, and felt a miraculous strength flowing into his limbs. In the meantime the glowing underbrush around him had become so dense that it cut off his view on all sides. To make matters worse, lianas and aerial roots were becoming inextricably tangled with the thicket below. Slashing with the side of his hand as if it had been a machete, Bastian opened up a passage. And the breach closed directly behind him as if it had never been. On he went, but the wall of giant tree trunks blocked his path. Bastian grabbed hold of two great tree trunks and bent them apart. When he had passed through, the wall closed soundlessly behind him. Bastian shouted for joy. He was the Lord of the Jungle! For a while he amused himself opening paths for himself, like an elephant that has heard the Great Call. His strength did not abate, he had no need to stop for breath. He felt no stitch in his side, and his heart didn’t thump or race. But after a while he wearied of his new sport. The next thing he wanted was to look down on his domain from above, to see how big it was.
