The teaching aspect of the Plan must now be pondered. Its challenge must be met, and its requirements studied, weighed, and fulfilled. Superb and irresistible as is the beauty of the first Mashriqu’l-Adhkár of the West, majestic as are its dimensions, unique as is its architecture, and priceless as are the ideals and the aspirations which it symbolizes, it should be regarded, at the present time, as no more than an instrument for a more effective propagation of the Cause and a wider diffusion of its teachings. In this respect it should be viewed in the same light as the administrative institutions of the Faith which are designed as vehicles for the proper dissemination of its ideals, its tenets, and its verities.
