恐れ多い is a Japanese word for something awe-inspiring or awesome (in some odd context, it can refer to August).

恐れ多い is probably not appropriate for a calligraphy wall scroll unless you have a specific reason.

The word awesome is misused a lot in English or used too casually. This Japanese word is the real form of awesome, and it kind of means numerous fears and anxiety that you would feel in response to encountering something truly awesome (such as God, a tornado, a tsunami, etc.).

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

把舵的不慌乘船的稳当 is a Chinese proverb that literally translates as: [If the] helmsman is not nervous, the passengers [will feel] secure.

Figuratively, this means: If the leader appears confident, his/her followers will gain confidence also.

This is a great suggestion that a confident leader inspires confidence in his/her troops or followers. Of course, a nervous leader will create fear in troops or followers.

靈感 is the Chinese word closest to hitting the mark for the English word inspiration.

In a more extended context, I have even seen this translated as “brain wave.”

The first character means alert, departed soul, efficacious, quick, effective, or intelligent.
The second character means to feel, to move, to touch, or to affect.
The combined meaning of these two characters changes a bit, but I think it's nice to know the individual meanings to give you a better understanding of where a word comes from.

You could describe this word as “the thought that pops into your head just before you patent the greatest widget ever invented that everyone in the world will want.”
At least, that's the idea.

This term can also mean “intelligent thought” if you translate it directly from each character. If you are looking for inspiration or need to be inspired, this is the word for you.

When the first character was absorbed into Japanese from Chinese, an alternate form became the standard in Japan. The Kanji shown to the right is the form currently used in Japan. This is still considered an alternate form in China to this day. it’s readable by both Chinese and Japanese people but if your audience is Japanese, I recommend the Kanji shown to the right - just click on that Kanji to order that version.

Beyond inspire or inspiration, 啟示 is a Chinese word that can mean enlightenment or revelation.

This is used as the Biblical revelation in the Chinese Bible, so it can also mean apocalypse depending on context.

Separately, the first character can mean: to open; to start; to initiate; to enlighten; to awaken; to state; to inform.

The second character alone can mean: to show; to reveal; to indicate; to proclaim.

勇気百倍 means to inspire someone with fresh courage or redoubled courage in Japanese.

The Kanji breakdown:
勇気 (yuuki) courage; bravery; valour; valor; nerve; boldness.
百 (hyaku) 100; hundred.
倍 (bai) twice; double; 2-times; 2-fold.

啟發 is a Chinese word that means to enlighten, arouse interest, inspire, inspiration, heuristics, or teach.

感奮 is a Chinese and Japanese word that means, moved and inspired, fired with enthusiasm, stirred up, moved to action, or state of being inspired.
