In her white dress, the Madonna resembles a lily, the symbol of innocence. But the beauty of the lilies  fades in Mary’s immaculate brilliance.

(Mieczyslaw Gogacz, Litania kwiatow do Matki Bozej)

 Mary, dressed like a lily in a simple white dress and trailing green net veil, stands among thorny plants, indicating that purity can overcome the temptations and trials of the world.
