The Ancient Beauty Has Consented to be Bound in Chains

Bound in Chains That ManKind May Be Released from Bondage...

The Ancient Beauty hath consented to be bound with chains that mankind may be released from its bondage, and hath accepted to be made a prisoner within this most mighty Stronghold that the whole world may attain unto true liberty. He hath drained to its dregs the cup of sorrow, that all the peoples of the earth may attain unto abiding joy, and be filled with gladness. This is of the mercy of your Lord, the Compassionate, the Most Merciful. We have accepted to be abased, O believers in the Unity of God, that ye may be exalted, and have suffered manifold afflictions, that ye might prosper and flourish. He Who hath come to build anew the whole world, behold, how they that have joined partners with God have forced Him to dwell within the most desolate of cities!
