Rudolf Steiner,
An Outline of Occult Science
“ Now we gaze in spirit on the rose and say to ourselves: “In the red sap of the rose is the erstwhile green sap of the plant—now changed to crimson—and the red rose follows the same pure, passionless laws of growth as does the green leaf.” Thus the red of the rose may offer us a symbol of a kind of blood which is the expression of cleansed impulses and passions, purged of all lower elements, and resembling in their purity the forces working in the red rose. Let us now try not only to assimilate such thoughts within our reason, but also let them come to life within our feelings. ”
