In short, all the time of the sojourn of the Blessed Perfection (Baha’u’llah)—May the souls of all existence be a ransom to His forbearance! —in this mortal world, He was either restrained with chains or kept under hanging swords, enduring the most painful afflictions. At last, in this greatest prison, His holy body was extremely weakened from the intense sufferings and His beautiful person became as weak as a web from this continual hardship. His main purpose in bearing this heavy burden and all these troubles, which gave forth their waves like an ocean, accepting the chains and fetters and showing forth the greatest forbearance, was for the sake of harmony, concord and union among all the people of the world and for the establishment of the signs of the real unity among all nations, until the essential Unity (of God) might (at last) appear in the existing realities, and the light of the saying: "Thou seest no difference among the creatures of God" might shine forth upon the whole world.
