Ah-un

"You approach Shinto shrines...and the entrances are usually guarded by a pair of stone lion-dogs...komu-inu, "Korean dogs"...One lion-dog has a mouth that is always open, the other has a mouth that is always closed. The open mouthed lion-dog is named Ah, the other is named Un, or more properly, nn. "Ah" is the first sound you make when you are born, "nn" the last sound you make when you die. "Ah" is the breath inhaled that begins life, "nn" the exhale of release, the breath that allows life to escape. Between the two lies all of existence, a universe that turns on a single breath. Ah is also the first symbol in the Japanese alphabet, n the last. And so, between these two lion-dogs, you also have the A and the Z, the Alpha and Omega. In the original Sanskrit, ah-un means, "the end and the beginning of the universe; infinity unleashed."

In Japan, people who are in perfect tune with each other, such as a pianist and a violinist playing in duet, are called ah/un-no-kokyu. Kokyu means "breathing," and the phrase suggests perfect, exquisite harmony: ah/un-no-kokyu, two or more breathing as one. If self-actualization is the ideal to which the Western world aspires, then common breath is the ideal to which Japan-and indeed, much of Asia-aspires. The word harmony in Japanese has the same cachet that the word freedom has in the West...

On a less esoteric level, ah-un also refers to old married couples (or even old friends) who have been together for so long that they no longer have to finish their sentences. One begins with "Ah..." and the other agrees with "Nn..." (which is the Japanese equivalent of "uh-huh") and the entire meaning is understood."
