Thoreau’s stellar vision wasn’t merely technique, a fun-pack of optical tricks. It was a function of character. He considered the perception of beauty “a moral test.” Beauty is not in the eye of the beholder. It is in his heart. We can’t improve our vision without improving ourselves. The dynamic works both ways. Not only does who we are determine what we see but what we see determines who we are. As the Vedas say, “What you see, you become.”
