Answer.—Consider the world of existence—that is to say, the world of material things. The solar system is dark and obscure, and in it the sun is the center of light, and all the planets of the system revolve around its might and are partakers of its bounty. The sun is the cause of life and illumination, and the means of the growth and development of all the beings of the solar system; for without the bounty of the sun no living being could exist: all would be dark and destroyed. Therefore, it is evident and clear that the sun is the center of light and the cause of the life of the beings of the solar system. In like manner, the Holy Manifestations of God are the centers of the light of reality, of the source of mysteries, and of the bounties of love. They are resplendent in the world of hearts and thoughts, and shower eternal graces upon the world of spirits; They give spiritual life and are shining with the light of realities and meanings. The enlightenment of the world of thought comes from these centers of light and sources of mysteries. Without the bounty of the splendor and the instructions of these Holy Beings the world of souls and thoughts would be opaque darkness. Without the irrefutable teachings of those sources of mysteries the human world would become the pasture of animal appetites and qualities, the existence of everything would be unreal, and there would be no true life. That is why it is said in the Gospel: “In the beginning was the Word,” meaning that it became the cause of all life.(131) Now consider the influence of the sun upon the earthly beings, what signs and results become evident and clear from its nearness and remoteness, from its rising or its setting. At one time it is autumn, at another time spring; or again it is summer or winter. When the sun passes the line of the equator, the life-giving spring will become manifest in splendor, and when it is in the summer solstice, the fruits will attain to the acme of perfection, grains and plants will yield their produce, and earthly beings will attain their most complete development and growth. In like manner, when the Holy Manifestation of God, Who is the sun of the world of His creation, shines upon the worlds of spirits, of thoughts and of hearts, then the spiritual spring and new life appear, the power of the wonderful springtime becomes visible, and marvelous benefits are apparent. As you have observed, at the time of the appearance of each Manifestation of God extraordinary progress has occurred in the world of minds, thoughts and spirits. For example, in this divine age see what development has been attained in the world of minds and thoughts, and it is now only the beginning of its dawn. Before long you will see that new bounties and divine teachings will illuminate this dark world and will transform these sad regions into the paradise of Eden.
