Global problems are becoming increasingly complex as the Earth's population grows and the relationships between nations become more intricate. It is important for the future of humanity to understand and harmonize with the spiritual laws and forces at work within the structure of culture, so that the individual – whether a person or a nation – can be in harmony with the evolving humanity.

Each nation, like a person, is subject to the influence of energies emanating from solar and cosmic sources. These energies affect the nation as a whole through the "reaction mechanism" corresponding to the tripartite constitution of the human being: Monad – soul – personality. Every nation is more receptive to certain energies than others, and all nations are subject to the evolution of national consciousness; they have their own destiny that literally relies on the properties and principles of the ray energy expressed through the national soul.

The recognition of the destiny of the souls of nations under the light of the teachings of this book has practical significance today as we seek international balance. The ray properties that influence peoples can be wisely utilized to foster understanding and unity.
