“In spiritual alchemy, the single red rose represents the mystic center of a person, his or her heart of hearts – one’s true nature. It also represents the process of purification to reveal one’s essence or the inner “pearl beyond price.”
“Alchemist Daniel Maier discusses the symbolism of the rose in his Septimana Philosophica: “The rose is the first, most beautiful and perfect of flowers. It is guarded because it is a virgin, and the guard is thorns. The Gardens of Philosophy are planted with many roses, both red and white, which colors are in correspondence with gold and silver. Virgin in the ancient world did not mean “untouched” it meant “untouchable.”
“Because of its association with the workings of the heart, the rose in alchemy has come to symbolize secrets of the heart or things that cannot be spoken or an oath of silence in general. In the folded structure of the rose, the flower seems to be concealing a secret inner core. “Mystery glows in the rose bed and the secret is hidden in the rose,” wrote the twelfth-century Persian alchemist Farid ud-din Attar.”
