”The face of him on whom I gazed I can never forget, though I cannot describe it. Those piercing eyes seemed to read one's very soul; power and authority sat on that ample brow…. No need to ask in whose presence I stood, as I bowed myself before one who is the object of a devotion and love which kings might envy and emperors sigh for in vain!" Bahá'u'lláh was thus described by the well-known Cambridge University Orientalist Edward Granville Browne in 1890. Bahá'u'lláh had, at that time, been a prisoner and an exile for almost 40 years and His teachings were shrouded in obscurity; today He is recognized by millions of followers around the world as the Manifestation of God or Divine Teacher for this age. According to Bahá'í belief, Manifestations of God, including Moses, Abraham, Christ, Muhammad, Krishna, and Buddha, have appeared at intervals throughout history to found the world's great religious systems. They have been sent by a loving Creator to enable us to know and to worship Him and to bring human civilization to ever higher levels of achievement. The station of these Manifestations is unique in creation. Their essential nature is twofold: they are at once human and divine. But they are not identical with God, the Creator, Who is Unknowable.
