The Eternal Feminine
That which draws us by its mystic force, that which every created thing…feels with absolute certainty at the very center of its being, that which Goethe here—again using an image—calls the Eternal Feminine—that is to say, the resting-place, the goal, as opposed to striving and struggling toward the goal (the eternal masculine)—that is the force of love, and you are right to call it by that name.
- Mahler in a letter to his wife, 1909
