初心 is often translated in Japanese as “beginner's mind” or “beginner's spirit.”

In Chinese, the dictionary definition is “one's original intention.”

The first character means first, initial, primary, junior, beginning, or basic.

The second character means heart, mind, soul, or essence.

初心 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: The state of shoshin is that of a beginners mind. It is a state of awareness that always remains fully conscious, aware, and prepared to see things for the first time. The attitude of shoshin is essential to continued learning.

初心流 is often translated in Japanese as “beginner's mind style,” “beginner's spirit method,” or “beginner’s-mind school”

The first character means first, initial, primary, junior, beginning, or basic.

The second character means heart, mind, soul, or essence.

The third character means style, method, or some will translate it as a school.

Please note, there is more than one martial arts school that romanizes as Shoshin-Ryu.

初心忘るべからず is an old Japanese proverb that suggests you try to never forget the enthusiasm you had as a child when you try new things (or even face the day-to-day). Basically, avoid having the mundane attitude that many people get with age.

You'll find this Japanese proverb translated in a few different ways. Here are some of them:
Don't forget your first resolution.
Never forget your childlike enthusiasm.
Forget not the beginner's mind.
Try never to lose your initial enthusiasm (freshness of attitude).

Note: This is sometimes written as 初心忘る可からず. The one shown above is used about 10x more often. There’s only one character difference between the two versions.

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