Humans have intimate connection to the Earth and Heaven
In Korean Chun-Ji-In means "Heaven, Earth, human." When they are combined into a single phrase they are used to remind individuals of their intimate connection to the ground they walk on and the air they breathe. Embracing this connection can result in a strong foundation for quests of spiritual growth.
Heaven, or the sky, is boundless and encompasses all things. It does not discriminate or force anything from its embrace. Instead, it is inclusive and welcoming and holds everything within its grasp.
The Earth provides all things with a solid footing, allowing them to pursue their lives with surety and a strong foundation.
The reference to human serves to remind everyone that they are still spiritual creatures that share an intimate connection to Heaven and the Earth.
When a person comes to appreciate this relationship, they develop a whole new understanding of their role in the Universe. They may see that they are actually a part of an endless chain that connects everything in existence.
This can be a powerful realization that stimulates searches for spiritual growth.
