A fish in water does not drown. A bird in the air does not plummet. Gold in fire does not perish. Rather, it gets its purity and its radiant color there. God has created all creatures to live according to their nature. How, then, am I to resist my nature? I must go from all things to God, Who is my Father by nature, My brother by His humanity, My bridegroom by love, And I His bride from all eternity.
–Mechthild of Magdeburg   (1208-1282)
