“Each thing must needs have an effect and each sign reveal a secret. Not until the world-illuming sun hath shone can the east be distinguished from the west, nor the blooming garden discerned from the barren waste. Heavenly strains compare not with earthly clamours, and the croaking of the raven can in no wise be confounded with the song of the nightingale. For the latter bespeaketh the land of the Beloved and increaseth life, whereas the former telleth only of the city of the blind and causeth faith to wither.“

– Bahá’u’lláh, The Call of the Divine Beloved
