先生 in Chinese / Japanese...

先生 is sensei, which is associated in the west with a master or instructor of karate, aikido, judo, and other Japanese martial arts.

In reality, this is a term of respect for almost any professional or skilled person (doctor, lawyer, teacher, etc.). Sometimes, it is used for musicians and artists who have achieved a certain level of fame, skill, or accomplishment.

It should be noted that this is also a courtesy title in Chinese but more like calling someone “mister” or “gentleman.” It doesn't have the “master” or “teacher” meaning in Chinese - see our Chinese “Master / Sifu / Shi Fu” entry if your audience is Chinese.

In Korean Hanja, this means teacher, instructor, schoolmaster, or schoolmistress.

This entry is for educational purposes. 先生 is kind of a strange thing to put on a wall scroll. It's a title that is used more orally to show respect rather than something written in calligraphy. If you feel it is appropriate in your circumstances, we will create a piece of sensei Japanese calligraphy artwork for you.

靈氣療法肇祖臼井甕男先生遺訓招福の秘法萬病の霊薬今日丈けは心配すな感謝して業を励げめ人に親切に is an alternate version of the precepts or tenets of Reiki by Usui Mikao.

It is impossible to be sure which version or versions were actually written by Usui Mikao. This is the less common of the three versions that you might see in the wild.

Here is a breakdown of the characters and a rough translation:
靈氣 療法 肇祖 臼井甕男。
Reiki therapy founder Mikao Usui
先生 遺訓。
Teacher's testament 招福の秘法,　萬病の霊薬。
Invite blessings of [the] secret method, 10,000 illnesses of spiritual medicine.
今日丈けは: 怒るな, 心配すな,　感謝して,　業をはげめ,　人に親切に。
At least for today: Do not be angry, do not worry, be grateful, work with diligence, [and] be kind to people.

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