Righteousness in Chinese / Japanese...

義を見てせざるは勇なきなり is a Japanese proverb that means “Knowing what is right and not doing is a want of courage.”

I've also seen it translated as:
To see what is right, yet fail to do so, is a lack of courage.
To know righteousness, but take no action is cowardice.
You are a coward if you knew what was the right thing to do, but you did not take action.
Knowing what is right without practicing it betrays one's cowardice.

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

正義 means justice or righteousness in Chinese, Japanese Kanji, and old Korean Hanja.

Practicing justice and righteousness is being fair.

It solves problems, so everyone wins. You don't prejudge. You see people as individuals. You don't accept it when someone acts like a bully, cheats, or lies. Being a champion for justice takes courage. Sometimes when you stand for justice, you stand alone.

Note: This is also considered to be one of the Seven Heavenly Virtues.

義 is about doing the right thing or making the right decision, not because it's easy but because it's ethically and morally correct.

No matter the outcome or result, one does not lose face if tempering proper justice.

義 can also be defined as righteousness, justice, morality, honor, or “right conduct.” In a more expanded definition, it can mean loyalty to friends, loyalty to the public good, or patriotism. This idea of loyalty and friendship comes from the fact that you will treat those you are loyal to with morality and justice.

義 is also one of the five tenets of Confucius's doctrine.

There's also an alternate version of this character sometimes seen in Bushido or Korean Taekwondo tenets. It's just the addition of a radical on the left side of the character. If you want this version, click on the image to the right instead of the button above.

This is also a virtue of the Samurai Warrior

忠義 is another form of loyalty or devotion.

In Chinese, this is more specifically about being loyal and devoted to your friends.

In Japanese, this is more often used to mean loyalty to your country or nation.

Except for the slight difference noted above between Japanese and Chinese, this word is understood universally in Chinese, Japanese Kanji, and old Korean Hanja. It can also be used to describe devotion or fidelity.

It should be noted that this Kanji combination is being used less and less in modern Japan (this is a better choice if your audience is Chinese, though any Japanese person will clearly understand it).

捨生取義 is a Chinese proverb that comes from the philosopher Mencius.

It can be translated in a few different ways:
To give up life for righteousness.
To choose honor over life
Better to sacrifice one's life than one's principles.

四拳波羅蜜大光明 is “shiken haramitsu daikōmyō,” a famous Japanese Buddhist mantra.

四拳 = shi-ken = four fists (many translate this as “four hearts”).
波羅蜜 = ha-ra-mitsu = A loanword representing pāramitā, or entrance into Nirvana. Awkwardly, it also means jackfruit.
大光明 = dai-kou-myo = big/great light bright (great bright light).

Shiken represents four hearts:
1. The Merciful Heart - Love and caring for all living things.
2. The Sincere Heart - Pursues righteousness, or the right path - sincerely trying to do what is right.
3. The Attuned Heart - Knows that nature and fate have their ways, and thus stay in tune with the universe.
4. The Dedicated Heart - Steadfast on the chosen path to the end.

布施 is the Buddhist practice of giving known as Dāna or दान from Pali and Sanskrit.

Depending on the context, this can be alms-giving, acts of charity, or offerings (usually money) to a priest for reading sutras or teachings.

Some will put Dāna in these two categories:
1. The pure or unsullied charity, which looks for no reward here but only in the hereafter.
2. The sullied almsgiving whose object is personal benefit.
The first kind is, of course, the kind that a liberated or enlightened person will pursue.

Others will put Dāna in these categories:
1. Worldly or material gifts.
2. Unworldly or spiritual gifts.

You can also separate Dāna into these three kinds:
1. 財布施 Goods such as money, food, or material items.
2. 法布施 Dharma, as an act to teach or bestow the Buddhist doctrine onto others.
3. 無畏布施 Courage, as an act of facing fear to save someone or when standing up for someone or standing up for righteousness.

The philosophies and categorization of Dāna will vary among various monks, temples, and sects of Buddhism.

Breaking down the characters separately:
布 (sometimes written 佈) means to spread out or announce, but also means cloth. In ancient times, cloth or robs were given to the Buddhist monks annually as a gift of alms - I need to do more research, but I believe there is a relationship here.
施 means to grant, to give, to bestow, to act, to carry out, and by itself can mean Dāna as a single character.

Dāna can also be expressed as 檀那 (pronounced “tán nà” in Mandarin and dan-na or だんな in Japanese). 檀那 is a transliteration of Dāna. However, it has colloquially come to mean some unsavory or unrelated things in Japanese. So, I think 布施 is better for calligraphy on your wall to remind you to practice Dāna daily (or whenever possible).

In short, 佛義 is the Principles of Buddhism, but there is more (especially for the second character):

佛 is the character for the Buddha and Buddhism.

義 has deeper meanings including justice, righteousness, morality, honour/honor, teachings, doctrine, right, proper, righteous, loyalty, purpose, or meaning. So the single word “principles” is often used to encompass all these ideas.

公義 means righteousness, justice, and/or equity in Chinese and Japanese.

Also a male given name, Masayoshi, in Japanese.
