On this chart were the chief landmarks of the region--the mountain with its forest, the desert with its green oases, the paths to the hidden springs. But there were not many details. The old cairns were not marked upon it, and when two paths led alike over the mountain, there was no sign to show that one was to be taken rather than the other. Not much was said as to what food one should take, or what raiment one should wear, or by what means one should defend himself. But there were many simple directions as to how one should act on the road, and by what signs he should know the right path. One ought to look upward, and not downward; to look forward, and not backward; to be always ready to give a helping hand to his neighbor: and whomsoever one meets is one's neighbor, he said. As to the desert, one need not dread it; nor should one fear the river, for the lands beyond it were sweet and fair. Moreover, one should learn to know the forest, that he might choose his course wisely. And this knowledge each one should seek for himself. For, as he said, "If the blind lead the blind, both shall fall into the ditch." There were many who followed his way and gave heed to his precepts. The path seemed dangerous at times, especially at the outset; for it lay along dizzy heights, through tangled underwood, and across swollen torrents. But after a while all these were left behind. The way passed on between cleft rocks, into green pastures, and by still waters; and in the desert were sweet springs which gave forth abundantly. But some who tried to follow him said that his Chart was not explicit enough. Every step in the journey, they contended, should be laid out exactly; for to travel safely one should never be left in doubt. Now, it chanced that on the slope of the mountain there was a huge granite rock, which stood in the midst of the way. Some of the travelers passed to the right of it, while others turned to the left. Strangely enough, the Chart said nothing concerning this rock. No hint was given as to how one should pass by it. When they came to the rock, many of the travelers took counsel one of another, and at last a great multitude was gathered there. Which way had he taken? For in the path he took they must surely go. Many scanned the rock on every side, to find if haply he had left some secret mark upon it. But they found none; or, rather, no one could convince the others that the hidden marks he found were intended for their guidance. At nightfall, after much discussion, the old men in the council gave their decision. The safe way led to the right. So he who kept the Chart marked upon it the place of the rock, and he wrote upon the Chart that the one true path leads to the right. Henceforth each man should know the way he must go.
