The phrase "There's poetry in nature. A symmetry" is a quote by Saffron A. Kent. It suggests that nature possesses both a poetic quality and a symmetrical structure, which serves as a source of inspiration and contemplation for poets and artists.

Being a nature and art lover, I always feel Mother Nature's so amazing in creating eye pleasing symmetric forms.
Found a nice description on Linkedin (https://www.linkedin.com/pulse/idioms-phrases-universe-himansu-sahu/):
"Full Moon is perfectly round. In fact, the Sun, the planets, and all celestial bodies are spherical in shape. The flowers have a number of petals (mostly five). One can rotate the flower around its axis by an angle equal to 2*pi divided by the number of petals, and the flower will still look the same. A butterfly is symmetric about its mid-axis. There are many more examples - a star, a snowflake, a jellyfish, the nautilus shell, the elegant hexagonal structure in a honeycomb, and so on. All of these exhibit some symmetry and lend themselves in some way or other, to the inherent beauty of nature, that we marvel at!"
True for human and animal bodies too, with single organs about our mid-axes and other parts symmetrically arranged. I can't imagine what they would look and function like otherwise. 
Sorry I have to go: Maowi the cat just came upstairs and announced his new business, asked me to take care of it asap.
But wait a minute: "Maowi, how come your nose fur colour isn't symmetric?"
