Fudoushin

If you click on the title of this post, you'll be directed to the http://www.answers.com/ page on "Fudoushin" or immovable mind, which is a martial arts concept.

A bit about the three characters which make up this word. The first character, " ", is like "not" or "un." It indicates that you should take the opposite meaning. UNlucky, for example. The second character, " ", is "movement," and in fact is made of two characters meaning "principal or important" and "power." The final character means "heart/mind."

You might have noticed that I've stuck a "u" between the "do" and "shin." This is how the word would be spelled in romaji, the Japanese version of our western alphabet.

From Answers.com:

Fudoshin (Japanese: 不動心) is a state of equanimity or imperturbability (literally and metaphorically "immovable heart" or "immovable mind") - a philosophical/mental dimension to a (commonly Japanese) martial art which contributes to the effectiveness of the advanced practitioner.

Fudoshin: A spirit of unshakable calm and determination, courage without recklessness, rooted stability in both mental and physical realms. Like a willow tree, powerful roots deep in the ground and a soft yielding resistance against the winds that blow through it.

Fudo Myo is a Buddhist guardian deity (and patron of martial arts) who is portrayed as carrying a sword in one hand (to cut through delusions and ignorance), and a rope in the other (to bind 'evil forces', and violent or uncontrolled passions and emotions). Despite a fearsome appearance, his aspects of benevolence and servitude to living beings are symbolized by a hairstyle associated with the servant class.
