Kokoro in Chinese / Japanese...

心の平和 means “heart of peace” or “peaceful heart” in Japanese.

月の心 means “Mind like the Moon” or, more directly translated, “Moon of Mind.”

月の心 is a phrase used in Zen Buddhism and some Japanese martial arts.

水の心 is the Japanese Buddhist and martial arts phrase, “Mizu no Kokoro,” which means “mind like water” or “heart of water.”

The phrase is a metaphor describing the pond that clearly reflects its surroundings when calm but whose images are obscured once a pebble is dropped into its waters.

心 would often be translated as “heart.”

However, because it was believed in Chinese culture for thousands of years that your consciousness and thoughts came from the big red organ in the middle of your chest, it also means “mind” or “spirit” and sometimes even “soul.”

In Korean, beyond heart, mind, and spirit, this character can mean moral, nature, mind, affections, intentions, core, and center. In fact, it is used in Chinese to mean “center” as well but only with another character in front of it. For instance, “medical center” or even “shopping center.” Separately and alone, it will not be read with that “center” meaning unless thought of as “the center of your soul.”

心を燃やせ is “Kokoro o Moyase” or “Set your heart ablaze” in Japanese.

Note: Because this selection contains some special Japanese Hiragana characters, it should be written by a Japanese calligrapher.

永遠に私の心の中に means “forever in my heart” or “always in my heart” in Japanese.

The character breakdown:
永遠 (eien) eternity; perpetuity; immortality; permanence.
に (ni) indicates the location of a person or thing.
私の (watashi no) my; mine.
心の中 (kokoro no naka) the middle of one's mind; the midst of one's heart.
に (ni) indicates the location of a person or thing (makes this “in” the middle of one's heart).

Note: There’s more than one way to say "Forever in My Heart" in Japanese, so you’ll find another version in our database. This is the very verbose version.

強い体強い心 is a way to write “strong mind, strong body” in Japanese.

Each of the two lines starts with 強い (tsuyoi) which means: strong; powerful; mighty; potent; resistant; resilient; durable; tough; stiff; hard; inflexible.

The body is represented with 体 (the ancient version is 體, romanized as karada), which means: body; build; physique; posture; torso; trunk; health.

Mind is represented with 心 (kokoro), which can mean heart, mind, or soul, depending on context.

強い體強い心 is not a common phrase in Japanese, so it's not the most natural title for calligraphy. In English, you might want to write it, “strong mind, strong body” but, “strong mind, strong body,” is more natural in Japanese.

In Japanese, 無心 means innocent or without knowledge of good and evil. It literally means “without mind.”

無心 is one of the five spirits of the warrior (budo) and is often used as a Japanese martial arts tenet. Under that context, places such as the Budo Dojo define it this way: “No mind, a mind without ego. A mind like a mirror which reflects and dos not judge.” The original term was “mushin no shin,” meaning “mind of no mind.” It is a state of mind without fear, anger, or anxiety. Mushin is often described by the phrase “Mizu no Kokoro,” which means “mind like water.” The phrase is a metaphor describing the pond that clearly reflects its surroundings when calm but whose images are obscured once a pebble is dropped into its waters.

This has a good meaning in conjunction with Chan / Zen Buddhism in Japan. However, out of that context, it means mindlessness or absent-mindedness. To non-Buddhists in China, this is associated with doing something without thinking.
In Korean, this usually means indifference.

Use caution and know your audience before ordering this selection.
