...the Guardian was very pleased to learn of the progress made by the Indian National Spiritual Assembly in its efforts to consolidate, widen and maintain the scope of its national activities. The difficulties in your way are tremendous. The differences of language and of social and intellectual background do, undoubtedly, render the work somewhat difficult to carry out and may temporarily check the efficient and smooth working of the national administrative machinery of the Faith. They, nevertheless, impart to the deliberations of the National Assembly a universality which they would be otherwise lacking, and give to its members a breadth of view which is their duty to cultivate and foster. It is not uniformity which we should seek in the formation of any National or Local Assembly. For the bedrock of the Bahá'í administrative order is the principle of unity in diversity, which has been so strongly and so repeatedly emphasized in the writings of the Cause. Differences which are not fundamental and contrary to the basic teachings of the Cause should be maintained, while the underlying unity of the administrative  order should be at any cost preserved and ensured. Unity, both of purpose and of means, is, indeed, indispensable to the safe and speedy working of every Assembly, whether local or national.
