It is that “marvelous collection of gem-like utterances, the “Hidden Words” with which Bahá’u’lláh was inspired, as He paced, wrapped in His meditations, the banks of the Tigris...” It is the “dynamic spiritual leaven cast into the life of the world for the reorientation of the mind of men, the education of their souls and the rectification of their conduct...” (Shoghi Effendi, God Passes By, p. 139).
