Everything in the natural world is full of design. The way each thing is designed helps it work. Shape, texture, color, strength — all of these things can be important.
When we recognize what something is, like a feather, we often stop looking further at it. By removing the use of your eyes, you explored each object in a new way, and “saw” them again as though for the very first time. This allowed you to discover new things about these familiar items, even better than if you used your eyes.
