Sixty years ago Bahá'u'lláh… advocated the establishment of
universal peace and the oneness of humanity. The Sháh of Persia and the Sultán
of Turkey threw us into prison. They killed twenty thousand of us hoping that
this Cause would be annihilated and that these teachings of Bahá'u'lláh would
be forgotten. But in spite of these obstacles the religion of Bahá'u'lláh
progressed day by day.
