Let's take two woodworkers, both who work with natural edge wood. Both do their best to select the best material for their furniture and both are equally successful.
However, one of them sells his furniture with a story - that he has found the "soul" of the tree and brought it into the furniture. The other woodworker just offers his furniture for sale, depending on the natural beauty of the wood and his craftsmanship.
Lo and behold, the guy with the story gets more sales at higher prices than the second woodworker. I suspect that Nakashima recognized that some buyers were gullible and would pay extra so that they could tell their friends the story that Nakashima told them.
Both woodworkers did the same thing, and produced the same final product - except for the story. The story didn't help Nakashima select better wood or better cuts - since a tree soul doesn't exist, searching for it is fruitless - but it helped him sell. He was a smart businessman - a good marketing person.
