Writing and etymology in Korean
週期 (주기) [chugi] - time period, cycle
性 (성) [seong] - nature, character

A cyclical relationship means unity. By starting them, we include a cycle of give-and-take action. The cyclical relationship is eternal because the movement in a circle is infinite. Likewise, time has no end because it is cyclical.

All of God’s creation is built on the principle of circular motion, thus reflecting an eternal nature. Even a man’s face has a rounded shape, though it is symmetrical. The human eye is shaped like a ball, and the upper and lower lips close the circumference of the mouth. The sun, moon, earth, and all the heavenly bodies are round. They revolve around their axis and around each other.

All the elements of the Universe are in a complementary give-and-take relationship. The give-and-take action occurs between the arteries and veins, providing blood circulation. Disease is essentially an imbalance of give-and-take action and a disruption of the cycle. Lack of give-and-take action between subject and object, interruption of this process leads to cessation of existence.

For the action to continue uninterrupted, subject-partner and object-partner must strive for the same goal, beneficial to both of them. If these conditions are not met, there will be no action. This is the immutable rule and law of the universe.

The more you love, the more love you receive. You have begun the give-and-take action, a virtuous cycle of ever-increasing giving. One day what you have given will come back to you, and the next time you will want to give even more. In this way, the sphere of giving expands.

The root of true love is the eternal cycle of giving. Giving adds strength, and constant acceptance reduces the strength you already have. The physics we are used to says that invested energy is expended, but according to the principle of love, giving leads to more energy. Whatever you give goes through a cycle and comes back to you-but in addition!
