Do-o is the Japanese equivalent of the Chinese word Tao, the order of nature. Raku means "enjoyment". To enjoy Tao (to live with appreciation all the time, wherever we are) is Do-o-Raku. When we are aware of nature's impartial and absolute justice, we know there is nothing to worry about. In Lin Chi's words: "At one stroke I forgot all my knowledge! There's no need for any discipline; for, move as I will, I always manifest the Tao!" When we see this, we can begin to enjoy our lives fully, by distributing infinite joy and thankfulness to everyone we meet.
Interestingly, Do-o-Raku also means "hobby". So we can say that Do-o-Raku means to live our life as a hobby - which is what it is! Anything we do is a game. It does not matter if we "fail" or "succeed". Such an understanding is Nirvana - eternal peace. In the words of Paramahansa Yogananda: "Do not take life's experiences too seriously . . . for in reality they are nothing but dream experiences. Play your part in life, but never forget that it is only a role."
To live in perpetual ecstatic delight is Do-o-Raku. Those who do so are called Do-o-Raku-Mono. If you are Do-o-Raku-Mono, you are Macrobiotic, whatever you eat.
