“What is a poet? An unhappy man who hides deep anguish in his heart, but whose lips are so formed that when the sigh and cry pass through them, it sounds like lovely music.... And people flock around the poet and say: 'Sing again soon' - that is, 'May new sufferings torment your soul but your lips be fashioned as before, for the cry would only frighten us, but the music, that is blissful.”
― Soren Kierkegaard, Either - Or

“The sad truth is that man's real life consists of a complex of inexorable opposites—day and night, birth and death, happiness and misery, good and evil. We are not even sure that one will prevail against the other, that good will overcome evil, or joy defeat pain. Life is a battleground. It always has been and always will be; and if it were not so, existence would come to an end.”
― C.G. Jung, Man and His Symbols

“People will do anything, no matter how absurd, in order to avoid facing their own souls. One does not become enlightened by imagining figures of light, but by making the darkness conscious.”
― Carl Jung, Psychology and Alchemy

“The unrealistic nature of these tales (which narrowminded rationalists object to) is an important device, because it makes obvious that the fairy tales’ concern is not useful information about the external world, but the inner process taking place in an individual.”
― Bruno Bettelheim, The Uses of Enchantment: The Meaning and Importance of Fairy Tales
