Unveiled and unconcealed, this Wronged One hath, at all times, proclaimed before the face of all the peoples of the world that which will serve as the key for unlocking the doors of sciences, of arts, of knowledge, of well-being, of prosperity and wealth. (Bahá'u'lláh, Tablets of Bahá'u'lláh revealed after the Kitáb-i-Aqdas; The Compilation of Compilations, vol. III, Social and Economic Development)
