I ran across a passage by Jeremy Taylor that I read and loved many years ago. The context is a comparison between the riches of Kings and the common riches we all enjoy, regardless of income. Here he contrasts the enjoyment a King may have gazing on his gold locked up in a little room and the jewels in his crown---
“For not to name the beauties and sparkling diamonds of heaven, a man’s or a woman’s or a hawks eye is more beautiful and excellent, then all the Jewels of his crown.”
What jewel can compare to the beauty of the eyes? And they are there for all the world to see, with no cost. I have thirteen grandchildren, and if they were all together, side by side, and all twenty six eyes were compared to the most expensive gemstones in the entire world, their eyes would captivate and out gleam the fairest stone.
