The spinner spun wool black like night. He bought it at the Asian market, from a seller with an authentically oriental name and sold only two things: silk and black wool. The seller swore that the shepherd that supplied the wool grazed his sheep by nigh and rested them by day. The spinner believed the seller's outrageous claims. He believed them because the seller's [silk worms was light as air and bright as a pearl.
The spinner knew that true things are always pure. Although his black wool was pure, he knew that purity does not always guarantee truth. But the spinner trusted the seller, because his wool was black like night.
And thus the spinner found that he spun truth.
