Perfect daysThe novelist Kim Yeon-soo wrote the novel "Perfect Days" of Mary Oliver, known in Korea, by quoting the poem "Geese" in the novel "Whoever Loves You". This beautiful and transparent prose of the Pulitzer Prize winning poet looks at the magnificent beauty of the planets amazing creatures and earth, including humans, and solves it in poets language. In it, we can see a brilliant but simple image drawn in language. "Perfect Days" is a collection of stories about Nature, his story, and his companion, Molly Malon Cook, around Provincetown. Through the prose of the poets life, the consciousness is dimly felt through the prose like music, which contains everything that makes up for oneself and oneself, the usual thoughts and the things that are realized in it. Some of them contain poetry, and Oliver says it is "a little hallelujah." Those poems say, "Just sit back and take a rest." Oliver, a natural poet and eco-poet, says that nature is as it is and now we are living here. Talking about the eagle that is pushed up during the ebb and trapped in the sand, the feeling of being baptized by the whale, Oliver invites readers to discover her own experience at the center of her world. Although it is comparable to Emerson and Thore in praising nature, Mary Oliver accepts nature as it is instead of looking at nature with human being centered. I find the beauty of "a very ordinary moment" in it.
