"This is a Book which hath become the Lamp of the Eternal unto the world ..."

"This is a Book which hath become the Lamp of the Eternal unto the world, and His straight, undeviating Path amidst the peoples of the earth. Say: This is the Dayspring of Divine knowledge, if ye be of them that understand, and the Dawning-place of God’s commandments, if ye be of those who comprehend."

-Bahá'u'lláh, The Kitáb-i-Aqdas, p.87
