寧靜 in Chinese / Japanese...

寧靜 expresses the idea of tranquility and serenity in Chinese.

寧靜致遠 is an ancient Chinese idiom that means “tranquility yields transcendence.”

This suggests pursuing a quiet life of profound study.

The first two characters mean tranquility. The last two characters mean “go far,” which suggests achieving much in your life or expanding beyond normal limits. The direct translation would read something like, “[With] tranquility [in your life, you'll] go far.”

Compare this to the English idiom: Still waters run deep.

寧靜而致遠 is five characters from a longer ten-character proverb composed by Zhuge Liang about 1800 years ago.

The proverb means “Your inner peace/tranquility/serenity will help you see or reach far (into the world).”

The last word means “far” but the deeper meaning is that you will surpass what you can currently see or understand. Perhaps even opening up vast knowledge and understanding of complex ideas.

內心的寧靜 is the long way to express the idea of “peace of mind” in Chinese.

The first two characters mean heart or “innermost being.”
The middle character is a connecting modifier.
The last two characters mean peace, tranquility, or serenity.

Some may also translate this as “inner peace,” but I like our other inner-peace options for that idea.

This kind of makes sense in Korean but will have an archaic read - even by those who can understand Korean Hanja.

淡泊以明志寧靜而致遠 is a kind of complex ten-character proverb composed by Zhuge Liang about 1800 years ago.

This is a Chinese proverb that means “Leading a simple life will yield a clear mind, and having inner peace will help you see far (into the world).”

What I have translated as “simple life” means NOT being materialistic and NOT competing in the rat race.

The last word means “far” but the deeper meaning is that you will surpass what you can currently see or understand. Perhaps even the idea of opening up vast knowledge and understanding of complex ideas.

The whole phrase has a theme that suggests if you are NOT an aggressive cut-throat person who fights his way to the top no matter how many people he crushes on the way, and instead seek inner peace, you will have a happier existence and be more likely to understand the meaning of life.
