…this civilization and material progress should be combined with the Most Great Guidance so that this nether world may become the scene of the appearance of the bestowals of the Kingdom, and physical achievements may be conjoined with the effulgences of the Merciful. This in order that the beauty and perfection of the world of man may be unveiled and be manifested before all in the utmost grace and splendour. Thus everlasting glory and happiness shall be revealed. 

- 'Abdu'l-Baha  (‘Selections from the Writings of ‘Abdu’l-Baha’)
