心の伴侶 is a Japanese-only title for soulmates.

心 means heart, soul, mind, core, or center. In ancient times, the heart was believed to be the mind or center of your soul and being.

の is a possessive article that connects everything here.

伴侶 means mates, companions, partners, and spouses.

This Japanese version of soulmates is about two partners, coupled or joined by their hearts.

姻緣 means “Destiny that brings lovers together.” It can also be translated technically as “Predestined matrimonial affinity” (wow, talk about taking the romance out of this word - that was from the Oxford C-E dictionary).

This speaks to the fate (or karma) that brings a husband and wife together. I would translate this as “Together by fate” or “Joined by destiny” but in the context of marriage. You could use this for non-married lovers, but the first character has a suggestion that this refers to those that are married.

愛は全てを完全に結ぶ帯である is a Japanese phrase that suggests we (or a couple) are bound together by love.

I searched the web and found all of these English translation variations for this phrase:

Have love; The only way in which you may be completely joined together.

Love is the sash that perfectly binds us together.

Love is what binds us together

Love binds all things together in perfect unity.

This same Japanese phrase is used as part of Colossians 3:14 in at least one version of the Japanese Bible.

A few Biblical versions include:

...Charity, which is the bond of perfectness. (KJV)

...Love, which binds them all together in perfect unity. (NIV)

克己奉公 is a Chinese proverb that is often used to express how one should act as a government official. Most of us wish our public officials would hold themselves to higher standards. I wish I could send this scroll, along with the meaning to every member of Congress, and the President (or if I was from the UK, all the members of Parliament, and the PM)

This can also mean: “Place Strict Standards on Oneself in Public Service.”
The story behind this ancient Chinese idiom:
Cai Zun was born in China a little over 2000 years ago. In 24 AD, he joined an uprising led by Liu Xiu, who later became the emperor of the Eastern Han Dynasty.

Later, the new emperor put Cai Zun in charge of the military court. Cai Zun exercised his power in strict accordance with military law, regardless of the offender's rank or background. He even ordered the execution of one of the emperor's close servants after the servant committed a serious crime.

Cai Zun led a simple life but put great demands on himself to do all things honorably. The emperor rewarded him for his honest character and honorable nature by promoting him to the rank of General and granting him the title of Marquis.

Whenever Cai Zun would receive an award, he would give credit to his men and share the reward with them.
Cai Zun was always praised by historians who found many examples of his selfless acts that served the public interest.
Sometime long ago in history, people began to refer to Cai Zun as “ke ji feng gong.”
