Make every effort to acquire the advanced knowledge of the day, and strain every nerve to carry forward the divine civilization. Establish schools that are well organized, and promote the fundamentals of instruction in the various branches of knowledge through teachers who are pure and sanctified, distinguished for their high standards of conduct and general excellence, and strong in faith; scholars and educators with a thorough knowledge of sciences and arts.

Included must be promotion of the arts, the discovery of new wonders, the expansion of trade, and the development of industry. The methods of civilization and the beautification of the country must also be encouraged...
