I recall, that when I read the book of Tao as a teen, there was one verse/chapter which really stuck with me. It went something like this:
If you have an ucarved block and you carve it into a spoon, then you have a spoon. But that spoon is worth less than the uncarved block because it is of one form whereas the uncarved block could be carved into a dragon. And if you carve the block into a dragon, then the dragon is worth less than the uncarved block. Because the block could be carved into anything, and has infinite forms.
However, searching through the texts I found on-line. I have found no such chapter. However, I have found references to this concept on Taoist websites. Is this chapter in the actual book of Tao, or was the text that I read as a teen somehow ammended?
