"I am a mountain, and I protect all living beings in the world."
"If you are a mountain, then I am a bird. I can just fly around you."
A mountain god from the spiritual world who cared about the world met the emperor from the heavenly realm who had gone through many calamities in the lower world. She thought they had nothing to do with each other, but the first calamity God gave her was a love calamity with him. The mountains are hard to find and the birds are hard to chase, but the two fell in love with each other and came together to stay together for life and eternity.
Purpose: If two people have a strong love for each other and have that determination, they will eventually be together even if they are in a foreign land.
