Etymology境 (경) [gyeong] - border, boundary, frontier
界 (계) [gye] - border
In a perfect world, there should be no boundaries between people. And in our world, no one likes them. But even for the simple act necessary to make someone happy, there are many boundaries to overcome. Can you feel it?
All boundaries came about because of selfishness. Let’s say two people are friends. They can go together, but as soon as one shows selfishness, their paths will diverge. You may think there are no boundaries in this situation, but showing selfishness always generates them. Even in a family, when parents and children disagree, invisible boundaries grow between them. The ideal is that in the end all boundaries should be destroyed, but how to get there?
When people unite around a common goal, boundaries will be unnecessary. True love should be the common goal of all mankind, a goal for which people will give up their selfish desires.
Where to find true love? It can be found in self-sacrifice. If a force could be found that could instill in the hearts of people a spirit of self-denial for others, even to the point of sacrificing their own lives, this would undoubtedly lead to unity.
The best way to destroy all boundaries between men and women, between parents and children, and at all levels of human relations is to sacrifice ourselves for others. A husband should live and sacrifice for his wife, a wife for her husband, etc. Sacrificial love and a sense of duty in relationships is the only absolute way to quickly destroy boundaries. Are there boundaries for the person who chooses to sacrifice himself for others? That person will be welcomed by all.
If you can overcome the limitations of loving someone, even if you have to give up your life, you can move forward. But as soon as you say that you are capable of sacrificing for that love to some limit, you will begin to move backward. Only true love can generate that kind of determination and desire.
