In our national anthem, there are these lyrics. “Until the tiny pebbles grow into massive boulders, lush with moss.” As the song goes, with the passing of time, small stones become boulders, and their surface becomes covered with moss.
This living moss is born from nature on a boulder with nothing on it. There is a mysterious power at work that cannot be seen with the eye. It is the power which causes life to be born. People of old called this mysterious power “Musu”.
