The word of Ki Raku (??)is the Japanese word combined two symbol word of Ki/energy and Raku/Enjoying.
The symbol, ? is used for music that is the art form expression in sound. This word" music" is originally from a Greek word, Muse. Goddes of sound muse is for music. Although the form of the letter appears to be non-resonance, a historical habitat of the context of expression human emotion seems very similar.
Wonder what we can relate to this enjoying energy and how we can adapt to consious better living?
