…when hatred and animosity, fighting, slaughtering, and great coldness of heart were governing this world, and darkness had overcome the nations, Bahá’u’lláh, like a bright star, rose from the horizon of Persia and shone with the great Light of Guidance, giving heavenly radiance and establishing the new Teaching.

He declared the most human virtues; He manifested the Spiritual powers, and put them into practice in the world around Him.
