"[Jesus] set before me the book of nature; I understood how all the flowers He has created are beautiful, how the splendor of the rose and the whiteness of the lily do not take away the perfume of the little violet or the delightful simplicity of the daisy. I understood that if all flowers wanted to be roses, nature would lose her springtime beauty, and the fields would no longer be decked out with little wild flowers."
--Saint Thérèse of the Child Jesus and of the Holy Face
A deceptively simple insight, that. Guess that's how one gets recognized as a Doctor of the Church.
