This maeans path of the warrior or warrior’s path in Japanese.

我行我素 is a way to say, “I walk my own path,” or “to continue in one's own way,” in Chinese.

This does not always have a completely positive connotation. It can mean ignoring advice or to persist in your path, no matter what others say or think.

八聖道 is one of two titles for the Buddhist Noble Eightfold Path.

This version specifically has the “noble” idea in the middle character, which also means holy, sacred, wise and good, or upright.

The other title also romanizes as Hasshoudou or Hasshōdō in Japanese but is written 八正道.

These are the eight tenets of the Buddhist Noble Eightfold Path written altogether.

Here's this list of tenets in English:
1. Right View / Right Understanding / Right Perspective / Perfect View
2. Right Resolve / Right Thought / Right Intention / Perfect Resolve
3. Right Speech / Right Talk / Perfect Speech
4. Right Action / Perfect Conduct
5. Right Living / Right Livelihood / Perfect Livelihood
6. Right Effort / Right Endeavor / Perfect Effort

見性成仏 or Kenshō Jōbutsu is the initial enlightenment that leads to self-awareness, becoming Buddha, and the path to enter Nirvana.

Kenshō Jōbutsu is a complex concept in Japanese Buddhism. 見性成仏 is probably better translated as “Seeing one’s nature and becoming a Buddha.”

大道無門 is a Buddhist proverb that means “The Great Way has no entrance,” “The Great Way is gateless,” or “The Great Path lacks a gate.”

This can be translated in many other ways.

This concept was authored within a long sacred text by 無門慧開 (known as Wúmén Huìkāi in Chinese or Mumon Ekai in Japanese). He was a Chinese Chan Master (in Japanese, a Zen Master) who lived between 1183 and 1260 AD. His most famous work was a 48-koan collection titled “The Gateless Barrier” or “The Gateless Gate” (無門關 Wú Mén Guān in Chinese, or 無門関 Mu Mon Kan in Japanese). This calligraphy title is a notable line from this collection.

I like this reference to the source of this proverb: The Gateless Gate 無門關

道諦 is the idea that once you have dealt with your desires and left all desire and attachment behind, only then are you on the path away from suffering (and on your way to enlightenment).

道諦 is also called the path to liberation in some English texts on Buddhism.

This term is exclusively used by devout Buddhists. It is not a common term, and is remains an unknown concept to most Chinese, Japanese and Korean people.
